Components of the male ultrasonic pulses are genetically based, but environmental temperature can affect the specific genotype's performance. As temperature increases, a lesser wax moth male's pulse rate increases and the female's acceptance threshold for rates increases. These changes most likely occur due to physiological effects, but the increase in pulse rate and acceptance threshold may also be used to avoid predation. Additionally, the increase in female acceptance threshold allows them to continue choosing the most attractive male by not mistaking a low-quality male for high-quality due to his new, faster pulse rate.
|
|
Respiration was generally not affected during these experiments. Subcutaneous administration of synephrine in doses ≤ 200 mg had no effects on blood pressure or pulse rate. Oral doses of 500–1500 mg of the drug did not affect blood pressure or respiration, but pulse rate was increased by ~12%, and the highest doses caused nausea and vomiting. The i.m.

In case of a baseband channel such as a telegraph line, a serial cable or a Local Area Network twisted pair cable, data is transferred using line codes; i.e., pulses rather than sinewave tones. In this case, the baud rate is synonymous to the pulse rate in pulses/second. The maximum baud rate or pulse rate for a base band channel is called the Nyquist rate, and is double the bandwidth (double the cut-off frequency).

These phases follow the course of: sensation of cold with shivering and malaise, high fever with a high or low pulse rate, profuse sweating inaugurating fever defervescence and an asthenic state, and aching.
|
|
Diving birds, such as penguins, have a similar diving reflex. The diving reflex is triggered by chilling the face and holding the breath. The cardiovascular system constricts peripheral blood vessels, slows the pulse rate, redirects blood to the vital organs to conserve oxygen, releases red blood cells stored in the spleen, and, in humans, causes heart rhythm irregularities. Aquatic mammals have evolved physiological adaptations to conserve oxygen during submersion, but apnea, slowed pulse rate, and vasoconstriction are shared with terrestrial mammals.

After detecting the lidar gun's light, the jammer will send out light on the same wavelength at a higher intensity, effectively confusing the gun into returning no speed reading. Newer laser jammer models can detect the pulse rate (the rate at which the gun takes distance measurements, upon which it bases the speed measurement) of the laser gun, and then emulate that pulse rate, further increasing the difficulty of getting an accurate reading from the laser gun. Because these jammers focus on blocking light emitted from laser guns, and not radio waves from radar guns, US federal laws prohibiting the use of radar jammers do not apply to these devices.

While the concept of a generation has a long history and can be found in ancient literature, there are also psychological and sociological dimensions in the sense of belonging and identity which may define a generation. The concept of a generation can be used to locate particular birth cohorts in specific historical and cultural circumstances, such as the "Baby boomers". Historian Hans Jaeger shows that, during this long history, two schools of thought coalesced regarding how generations form: the "pulse-rate hypothesis" and the "imprint hypothesis." According to the pulse-rate hypothesis, a society's entire population can be divided into a series of non-overlapping cohorts, each of which develops a unique "peer personality" because of the time period in which each cohort came of age.

This is important for two reasons. One, an ECG may give a ventricular contraction rate that does not correspond to the palpated pulse rate. Secondly, because not all beats are being conducted, patients may present with symptoms of low output heart failure, e.g. Dizziness, shortness of breath or hypotension, even with a normal ECG.
|
|
The Jarisch-Herxheimer reaction is also the name given to a reaction often precipitated by treatment of relapsing fevers. It usually begins within a few hours of the first dose and causes an initial rise in temperature, pulse rate and blood pressure, then followed by marked vasodilation and sweating, which can result in shock.

|
The time depends on pulse rate, pulmonary function, RBC count, and other metabolic factors. Lidocaine can be given in 1.5 mg/kg IV a few minutes before sedation and paralysis. The purpose of administering lidocaine is to blunt the sympathetic response of an increased heart rate, blood pressure, and intracranial pressure caused by laryngoscopy. Atropine can be given when children produce a vagal response, evidenced by bradycardia, in response to intubation.

|
Measured variables are any one of several attributes of people that may be observed and measured. Examples of measured variables could be the physical height, weight, and pulse rate of a human being. Usually, researchers would have a large number of measured variables, which are assumed to be related to a smaller number of "unobserved" factors. Researchers must carefully consider the number of measured variables to include in the analysis.

Pulsus paradoxus, also paradoxic pulse or paradoxical pulse, is an abnormally large decrease in stroke volume, systolic blood pressure and pulse wave amplitude during inspiration. The normal fall in pressure is less than 10 mmHg. When the drop is more than 10 mmHg, it is referred to as pulsus paradoxus. Pulsus paradoxus is not related to pulse rate or heart rate, and it is not a paradoxical rise in systolic pressure.

Sometimes the variations are large. Hypertension refers to arterial pressure being abnormally high, as opposed to hypotension, when it is abnormally low. Along with body temperature, respiratory rate, and pulse rate, blood pressure is one of the four main vital signs routinely monitored by medical professionals and healthcare providers. Measuring pressure invasively, by penetrating the arterial wall to take the measurement, is much less common and usually restricted to a hospital setting.

Jean Fernel (1497–1558), a French physician, introduced the term "physiology". Galen, Ibn al-Nafis, Michael Servetus, Realdo Colombo, Amato Lusitano and William Harvey, are credited as making important discoveries in the circulation of the blood. Santorio Santorio in 1610s was the first to use a device to measure the pulse rate (the pulsilogium), and a thermoscope to measure temperature. In 1791 Luigi Galvani described the role of electricity in nerves of dissected frogs.

Vollmer was born in Syracuse, New York, and raised in the Dallas-Fort Worth Metroplex region in Granbury, Texas. As an age group swimmer, Vollmer swam for coach Ron Forrest at the Fort Worth Area Swim Team (FAST). In 2003, Vollmer underwent heart surgery to correct a condition called supraventricular tachycardia, which produces a quickened pulse rate of about 240 beats per minute. After that surgery, an electrocardiogram indicated to her cardiologists that she might have Long QT syndrome.

Despite this, Clay taunted Liston during the pre-fight buildup, dubbing him "the big ugly bear", stating "Liston even smells like a bear" and claiming "After I beat him I'm going to donate him to the zoo."[ Remnick (1998), p. 147] Clay turned the pre-fight weigh-in into a circus, shouting at Liston that "someone is going to die at ringside tonight." Clay's pulse rate was measured at 120, more than double his normal 54.

Some of the thermal insulation tore loose, raising the cabin temperature to . After three hours of weightlessness, Laika's pulse rate had settled back to 102 beats/min, three times longer than it had taken during earlier ground tests, an indication of the stress she was under. The early telemetry indicated that Laika was agitated but eating her food. After approximately five to seven hours into the flight, no further signs of life were received from the spacecraft.

Following an oral single dose of 20 mg peak plasma concentrations are reached within 1–2 hours. The effect of pindolol on pulse rate (lowering) is evident after 3 hours. Despite the rather short halflife of 3–4 hours, hemodynamic effects persist for 24 hours after administration. Plasma halflives are increased to 3-11.5 hours in patients with renal impairment, to 7–15 hours in elderly patients, and from 2.5–30 hours in patients with liver cirrhosis.

A pulse watch, also known as a pulsometer or pulsograph, is an individual monitoring and measuring device with the ability to measure heart or pulse rate. Detection can occur in real time or can be saved and stored for later review. The pulse watch measures electrocardiography (ECG or EKG) data while the user is performing tasks, whether it be simple daily tasks or intense physical activity. The pulse watch functions without the use of wires and multiple sensors.
|
|
The original design of the pulse watch has undergone major development since 1707. With modern advancements in technology, the pulse watch which could once only read a users' pulse rate has progressed into a smart device capable of much more. The advancements of these devices have allowed for specific health related behaviours to be counteracted with the use of these technologies. Smokewatch, a smartwatch company is designing a watch used to aid in the process of smoking cessation.

Huchard was a member of the Académie de Médecine. Huchard specialized in the study of cardiovascular disease, and is remembered for his research of arteriosclerosis. His name is lent to "Huchard's disease" (continued arterial hypertension), Online ICD9/ICD9CM codes and to "Huchard's sign", which is an indication of hypertension, and defined as a pulse rate that does not decrease when changing from a standing to a supine position. Huchard married Berthe Gilbert with whom he had two sons.

TQIP measures multiple variables in its risk-adjustment models. These variables include factors such as age, race, gender, initial pulse rate in the emergency department, the mechanism of injury, etc. An 18 variable multivariable logistic regression model is used to estimate risk-adjusted mortality for trauma patients. Results provide observed-to-expected ratios and a 90% confidence interval of a trauma center's data compared to other de-identified trauma centers in order to gauge relative variability.

This means for a wavelength of 5 cm (as shown in the diagram), an unambiguous velocity range of 12.5 to 18.75 metre/second is produced (for 150 km and 100 km, respectively). For a 10 cm radar such as the NEXRAD, the unambiguous velocity range would be doubled. Some techniques using two alternating pulse repetition frequencies (PRF) allow a greater Doppler range. The velocities noted with the first pulse rate could be equal or different with the second.
|
|
Radar systems operating at a PRF below about 3 kHz pulse rate produce true range, but produce ambiguous target speed. Radar systems operating at a PRF above 30 kHz produce true target speed, but produce ambiguous target range. Medium PRF systems produce both ambiguous range measurement and ambiguous radial speed measurement using PRF from 3 kHz to 30 kHz. Ambiguity resolution finds true range and true speed by using ambiguous range and ambiguous speed measurements with multiple PRF.
|
|
Systems using PRF below 3 kHz are considered low PRF because direct range can be measured to a distance of at least 50 km. Radar systems using low PRF typically produce unambiguous range. Unambiguous Doppler processing becomes an increasing challenge due to coherency limitations as PRF falls below 3 kHz. For example, an L-Band radar with 500 Hz pulse rate produces ambiguous velocity above 75 m/s (170 mile/hour), while detecting true range up to 300 km.

The Baton was also equipped with sensors that detected and monitored the Runner's pulse rate. This information was then conveyed to a series of light-emitting diodes (LEDs), via a light behaviour module. The lens then transformed the LEDs into a shaft of bright blue pulsating light which synchronised with each new Runner. The hearts of the Runner and the Baton then beat as one until it was passed on, symbolising the journey of humanity and the essence of life.

The Air Ministry also adopted this system as a mobile auxiliary to the CH system. In early 1938, Butement started the development of a CD system based on Bowen's evolving 200-MHz (1.5-m) airborne sets. The transmitter had a 400 Hz pulse rate, a 2-μs pulse width, and 50 kW power (later increased to 150 kW). Although many of Bowen's transmitter and receiver components were used, the system would not be airborne so there were no limitations on antenna size.

In digital communications, symbol rate, also known as baud rate and modulation rate, is the number of symbol changes, waveform changes, or signaling events across the transmission medium per time unit using a digitally modulated signal or a line code. The symbol rate is measured in baud (Bd) or symbols per second. In the case of a line code, the symbol rate is the pulse rate in pulses per second. Each symbol can represent or convey one or several bits of data.

The flight cassettes containing the newts were retrieved approximately six hours after landing. Some of the larvae were fixed and preserved for later analysis, while some were tested to estimate how space flight affected the gain of the otolith-ocular reflex and measure the otolith volumes and areas of associated sensory epithelia. Living jellyfish were counted, coded, and photographed beginning at five hours postflight. The pulse rate, numbers of arms, rhopalia, and statoliths were counted in each of the ephyrae.

The laser array is rotated 2 degrees from the satellite's ground track so that a beam pair track is separated by about . The laser pulse rate combined with satellite speed results in ATLAS taking an elevation measurement every along the satellite's ground path. The laser fires at a rate of 10 kHz. Each pulse sends out about 200 trillion photons, almost all of which are dispersed or deflected as the pulse travels to Earth's surface and bounces back to the satellite.

He practised in Lichfield, and it was by his advice that Dr Johnson, when a child, was taken by his mother to be touched by Queen Anne for the king's evil on 30 March 1714. As a physician, Floyer was best known for introducing the practice of pulse rate measurement, and creating a special watch for this purpose. He was an advocate of cold bathing, and gave an early account of the pathological changes in the lungs associated with emphysema.

Antiochus, the son of King Seleucus, is pining away yet he would rather die than name the cause of his disease to his father. The doctor, Erasistratus, suspects love is behind Antiochus's suffering. He notices that the prince's pulse rate increases when he sees Stratonice, a young woman intended as his father's bride, and further tests confirm his diagnosis. The doctor subtly reveals the truth to the king who is content to relinquish Stratonice to Antiochus to save his son's life and happiness.

" When following the imprint hypothesis, social scientists face a number of challenges. They cannot accept the labels and chronological boundaries of generations that come from the pulse-rate hypothesis (like Generation X or Millennial); instead, the chronological boundaries of generations must be determined inductively and who is part of the generation must be determined through historical, quantitative, and qualitative analysis. While all generations have similarities, there are differences among them as well. A 2007 Pew Research Center report called "Millennials: Confident. Connected.

Doppler systems involve velocity measurements similar to the kind of measurements made using a strobe light. For example, a strobe light can be used as a tachometer to measure rotational velocity for rotating machinery. Strobe light measurements can be inaccurate because the light may be flashing 2 or 3 times faster than shaft rotation speed. The user can only produce an accurate measurement by increasing the pulse rate starting near zero until pulses are fast enough to make the rotating object appear stationary.

The effectiveness of electrofishing is influenced by a variety of biological, technical, logistical, and environmental factors. The catch is often selectively biased as to fish size and species composition. When using pulsed DC for fishing, the pulse rate and the intensity of the electric field strongly influence the size and nature of the catch. The conductivity of the water influences the shape and extent of the electric field and thus affects the field's ability to induce capture-prone behavior in the fish.

Serafina is also able to detect genetic and bio-chemical data down to the molecular level. This makes her an extraordinary tracker, capable not only of tracing a target's path but also identifying any person or object they might have touched and recognizing subtle shifts in their body chemistry or metabolism, such as changes in adrenaline levels or pulse rate. She can also manipulate bio- molecular ingredients to some degree. Aguja (Needle): She possesses powers that include the projection of energy blasts and force fields.

The integral (4) crosses the threshold in half the time in the right column than in the left column. Thus the frequency of impulses is doubled. Hence the count increments at twice the speed on the right to that on the left; this pulse rate doubling is consistent with the input voltage being doubled. Construction of the waveforms illustrated at (4) is aided by concepts associated with the Dirac delta function in that, by definition, all impulses of the same strength produce the same step when integrated.

Siegelman stated that he had received an honorable discharge as the result of several physical symptoms including high blood pressure, high pulse rate, headaches, and dizziness that were attributed to stress over family concerns including the illness of his father. He earned a J.D. degree from Georgetown University Law Center in Washington, D.C., in 1972. He studied international law at the University of Oxford from 1972 to 1973. While at the University of Alabama, Siegelman served as the president of the student government association.

LESS attitude control varied widely among designs. Some used the main engine for attitude control by gimballing the engine nozzle to alter the direction of thrust. Others had multiple engines and could use relative throttling or pulse-rate to vary the thrust from the different engines and control attitude that way. A few used cold gas RCS thrusters where high-pressure gas (typically nitrogen) was released from nozzles to provide a small amount of thrust without endangering the crew with hot gas from a rocket thruster.

The Italian tree frog is able to climb bushes and trees and move around the countryside via hedgerows, ditches and canals. It feeds on small invertebrates such as flies, mosquitoes and midges. In the breeding season, dominant males establish territories near a pond, paddy field, or other area of water and advertise themselves by calling. Each call consists of a repeated series of six to ten pulses which start quietly and increase in intensity and which varies in frequency and pulse rate between different males.
|
|
The diet of this frog consists of ants, termites and many other tiny insects. It breeds in ponds, permanent pools or marshy areas and the males call at night, several neighboring frogs making a chorus and producing a song that sounds like the sounds made by crickets. The call has a frequency of between 3 and 3.2 kHz, with a pulse rate of 14–20 pulses per second, and a duration of less than a second. Females lay small clutches of about 20 eggs.

Typical duration of the test ranges ten to twenty minutes. Adults who are beginning a new exercise regimen are often advised to perform this test only in the presence of medical staff due to risks associated with high heart rates. For general purposes, a formula is often employed to estimate a person's maximum heart rate. However, these predictive formulas have been criticized as inaccurate because they generalized population-averages and usually focus on a person's age and do not even take normal resting pulse rate into consideration.

Among many other features, CIS presents non-simultaneous pulses to the different electrodes in the implant, which greatly reduces deleterious interactions, or crosstalk, among the electrodes. Other signal coding strategies developed and implemented in his laboratory include predecessors of the Fine Structure Processing (FSP, FS4) strategies and of the Fidelity120 virtual channel strategy. In collaboration with Cochlear Americas, Duke University and the NIH, Wilson's group also developed and evaluated a high pulse rate, channel-picking strategy. A direct outcome was the advanced combination encoder, or ACE strategy.

The figure below shows an example of a generalized pulsed radio frequency waveform as seen with an oscilloscope with an antenna probe. In this example there are 1000 pulses per second (one kilohertz pulse rate) with a gated pulse width of 42 μs. The pulse packet frequency in this example is 27.125 megahertz (MHz) of RF energy. The duty cycle for a pulsed radio frequency is the percent time the RF packet is on, 4.2% for this example ([0.042 ms X 1000 pulses divided by 1000 ms/s] X 100).

In communications technologies without forward error correction and other physical layer protocol overhead, there is no distinction between gross bit rate and physical layer net bit rate. For example, the net as well as gross bit rate of Ethernet 10Base-T is 10 Mbit/s. Due to the Manchester line code, each bit is represented by two pulses, resulting in a pulse rate of 20 megabaud. The "connection speed" of a V.92 voiceband modem typically refers to the gross bit rate, since there is no additional error-correction code.

Eggs Toads emerge from hibernation in early May to go to the north shore for mating. They return to the souths shore by late September or early October for hibernation. The younger toads of the year were active up to one month later than older toads which gives them more time to store energy for hibernation and reduce intraspecific competition. The mating calls of the Wyoming toad has a low frequency along with a slow pulse rate, but the duration is longer than that of other types of toads.

Before the next laser pulse can be transmitted the previous one must have had time to travel to the far end of the fiber and for the reflections from there to return, otherwise reflections would be returning from different sections of the fiber at the same time and the system would not operate properly. For a fiber 50 km long the maximum pulse rate is just over 2 kHz. Therefore, strains can be measured which vary at frequencies up to the Nyquist frequency of 1 kHz. Shorter fibers clearly enable higher acquisition rates.

A digital differential analyzer (DDA), also sometimes called a digital integrating computer, is a digital implementation of a differential analyzer. The integrators in a DDA are implemented as accumulators, with the numeric result converted back to a pulse rate by the overflow of the accumulator. The primary advantages of a DDA over the conventional analog differential analyzer are greater precision of the results and the lack of drift/noise/slip/lash in the calculations. The precision is only limited by register size and the resulting accumulated rounding/truncation errors of repeated addition.

Those who are lying and those who are telling the truth possess different forms of nonverbal and verbal cues and this is important to keep in mind. In addition, it is important to note that understanding the cultural background of a person will influence how easily deception is detectable because nonverbal cues may differ depending on the culture. In addition to eye contact these nonverbal cues can consist of physiological aspects including pulse rate as well as levels of perspiration. In addition eye aversion can be predictive of deception.

Levosalbutamol acts as a functional agonist that relaxes the airway irrespective of the spasmogen involved, thereby protecting against all bronchoconstrictor challenges. While it is recognized that β2 adrenergic receptors are the predominant receptors on bronchial smooth muscle, data indicate that there are beta receptors in the human heart, 10–50% of which are β2 adrenergic receptors. The precise function of these receptors has not been established. However, all β adrenergic agonist drugs can produce a significant cardiovascular effect in some patients, as measured by pulse rate, blood pressure, and restlessness symptoms, and/or electrocardiographic (ECG).

A pulse oximeter probe applied to a person's finger A pulse oximeter is a medical device that indirectly monitors the oxygen saturation of a patient's blood (as opposed to measuring oxygen saturation directly through a blood sample) and changes in blood volume in the skin, producing a photoplethysmogram that may be further processed into other measurements. The pulse oximeter may be incorporated into a multiparameter patient monitor. Most monitors also display the pulse rate. Portable, battery-operated pulse oximeters are also available for transport or home blood-oxygen monitoring.

The pulse is commonly taken at the wrist (radial artery). Alternative sites include the elbow (brachial artery), the neck (carotid artery), behind the knee (popliteal artery), or in the foot (dorsalis pedis or posterior tibial arteries). The pulse is taken with the index finger and middle finger by pushing with firm yet gentle pressure at the locations described above, and counting the beats felt per 60 seconds (or per 30 seconds and multiplying by two). The pulse rate can also be measured by listening directly to the heartbeat using a stethoscope.

The operation occurred on September 6, 1891 at the City Hospital, on a twenty-two- year-old man who had been stabbed in the chest. Upon arrival of the patient, Dalton cleaned the wound and applied a dressing of antiseptic gauze. After several hours, the patient's condition worsened: the left side of his chest became dull to percussion; his temperature and pulse rate rose; his breathing became shallow; and he complained of considerable pain. He was taken to the surgical amphitheatre, where Dalton made an incision over the fourth rib and removed about of it.

Diving birds, such as penguins, have a similar diving reflex. The diving reflex is triggered specifically by chilling the face and breath-hold. The most noticeable effects are on the cardiovascular system, which displays peripheral vasoconstriction, slowed pulse rate, redirection of blood to the vital organs to conserve oxygen, release of red blood cells stored in the spleen, and, in humans, heart rhythm irregularities. Aquatic mammals have evolved physiological adaptations to conserve oxygen during submersion, but the apnea, bradycardia, and vasoconstriction are shared with terrestrial mammals as a neural response.

However, it also caused problems for the Germans, as it sometimes detected stray radar emissions from distant ships or planes, causing U-boats to submerge when they were not in actual danger, preventing them from recharging batteries or using their surfaced speed. Metox provided the U-boat commander with an advantage that had not been anticipated by the British. The Metox set beeped at the pulse rate of the hunting aircraft's radar, approximately once per second. When the radar operator came within of the U-boat, he changed the range of his radar.

The substance is used in the production of jet fuel, in pesticides, plastics, pulp mills and oil refineries and can cause irritation of the skin and eyes, nausea, vomiting, increases in pulse rate and blood pressure, hemolytic anemia, respiratory problems, narcosis, dizziness, convulsions, staggering gait and weakness in the muscles. It is lethal in large doses. According to officials gas capsules with timers were found in three other Maksidom shops in the city. The Associated Press news agency reported that the chain had received letters threatening to disrupt sales during the holiday period.

At the end of 1978, Clark and Tong made a ground-breaking discovery. The speech processing strategy coded the second formant as place of stimulation along the cochlear array, the amplitude of the second formant as current level, and the voicing frequency as pulse rate across the formant channels. Clark in December 1978 arranged that his audiologist present open- set words to his first patient, who was able to identify several correctly. As a result, Clark went on to operate on a second patient who had been deaf for 17 years.

Non-laser light detection is utilized extensively in automated machine control systems (e.g. electric eyes controlling a garage door, conveyor sorting gates, etc.), and those that use pulse rate detection and ranging are at heart, the same type of system as a radar--without the bells and whistles of the human interface. Unlike lower radio signal frequencies, light does not bend around the curve of the earth or reflect off the ionosphere like C-band search radar signals, and so lidar is useful only in line of sight applications like higher frequency radar systems.

In his introduction to Borg's autobiography My Life and Game, Eugene Scott relates that this rumor arose from a medical exam the 18-year-old Borg once took for military service, where his pulse was recorded as 38. Scott goes on to reveal Borg's true pulse rate as "about 50 when he wakes up and around 60 in the afternoon."Borg, Björn, and Eugene L. Scott. My Life and Game (1980), page 11 Borg is credited with helping to develop the style of play that has come to dominate the game today.

In his early research, Judd and his collaborators showed that the ovaries of postmenopausal women could secrete amounts of androgen, which can act as precursors to estrogen. He then began investigating the physiology of hot flushes, a characteristic symptom of menopause. He developed techniques to monitor the onset and severity of hot flushes, using electrodes to measure rises in skin temperature due to vasodilation, and pulse rate. These objective measurements of hot flushes later assisted in assessing the effectiveness of treatments mitigating the signs and symptoms of menopause, including hormone replacement therapy.

As an example, an antenna with a 2 degree beam with a pulse rate of 1 kHz will require approximately 8 seconds to cover an entire hemisphere consisting of 8,000 pointing positions. This configuration provides 12 opportunities to detect a vehicle over a range of , which is suitable for military applications. The position of mechanically steered antennas can be predicted, which can be used to create electronic countermeasures that interfere with radar operation. The flexibility resulting from phased array operation allows beams to be aimed at random locations, which eliminates this vulnerability.

Due to its highly coveted fragrance, the essential oil produced from Sandalwood is often used in aromatherapy and is added to soaps and cosmetics. It is also used in Ayurvedic medicine for the treatment of both somatic and mental disorders, including common colds, bronchitis, fever, urinary tract infections, and inflammation. In some cases, positive effects combatting ferret anxiety with sandalwood have been observed. A study investigating the effects of inhalation of East Indian sandalwood oil and its main compound, α-santalol, on human physiological parameters found that the compounds elevated pulse rate, skin conductance, and systolic blood pressure.

The Oculocardiac reflex, also known as Aschner phenomenon, Aschner reflex, or Aschner–Dagnini reflex, is a decrease in pulse rate associated with traction applied to extraocular muscles and/or compression of the eyeball. The reflex is mediated by nerve connections between the ophthalmic branch of the trigeminal cranial nerve via the ciliary ganglion, and the vagus nerve of the parasympathetic nervous system. Nerve fibres from the maxillary and mandibular divisions of the trigeminal nerve have also been documented. These afferents synapse with the visceral motor nucleus of the vagus nerve, located in the reticular formation of the brain stem.

A target designator Another military use of lasers is as a laser target designator. This is a low-power laser pointer used to indicate a target for a precision-guided munition, typically launched from an aircraft. The guided munition adjusts its flight-path to home in to the laser light reflected by the target, enabling a great precision in aiming. The beam of the laser target designator is set to a pulse rate that matches that set on the guided munition to ensure munitions strike their designated targets and do not follow other laser beams which may be in use in the area.

Even constant monitoring of the blood pressure and the pulse rate can lead to some conclusion regarding angina. The exercise test is also useful in looking for other markers of myocardial ischemia: blood pressure response (or lack thereof, in particular, a drop in systolic blood pressure), dysrhythmia and chronotropic response. Other alternatives to a standard exercise test include a thallium scintigram or sestamibi scintigram (in patients unable to exercise enough for the purposes of the treadmill tests, e.g., due to asthma or arthritis or in whom the ECG is too abnormal at rest) or stress echocardiography.

Emergency department studies have shown that SpCO helps clinicians increase the detection of carbon monoxide (CO) poisoning and decreases the time to treatment compared to invasive methods. The Pronto-7 device for noninvasive spot checking of hemoglobin, along with SpO2 and pulse rate, has been recognized with a gold Medical Design Excellence Award. The World Health Organization called noninvasive hemoglobin an "innovative medical technology for cost-effectively addressing global health concerns and needs". In October 2014, Masimo announced CE Mark of Oxygen Reserve Index or ORi, the company's 11th noninvasive parameter, which provides real-time visibility to oxygenation status.

In 1927, Nyquist determined that the number of independent pulses that could be put through a telegraph channel per unit time is limited to twice the bandwidth of the channel. In symbolic notation, :f_p \le 2B where f_p is the pulse frequency (in pulses per second) and B is the bandwidth (in hertz). The quantity 2B later came to be called the Nyquist rate, and transmitting at the limiting pulse rate of 2B pulses per second as signalling at the Nyquist rate. Nyquist published his results in 1928 as part of his paper "Certain topics in Telegraph Transmission Theory".

Digital meters employ oscillometric measurements and electronic calculations rather than auscultation. They may use manual or automatic inflation, but both types are electronic, easy to operate without training, and can be used in noisy environments. They measure systolic and diastolic pressures by oscillometric detection, employing either deformable membranes that are measured using differential capacitance, or differential piezoresistance, and they include a microprocessor.Oscillometry, Explanation of oscillometric detection in Medical Electronics, N Townsend, p48-51 They measure mean blood pressure and pulse rate, while systolic and diastolic pressures are obtained less accurately than with manual meters, and calibration is also a concern.

Vasopressin receptors activated by vasopressin are found on the basolateral membrane of the cells lining the collecting ducts of the kidneys. Aneurysmal subarachnoid hemorrhage(aSAH) results in hyponatremia which leads to water retention and antidiuretic hormone release causing increase in intracranial pressure and formation of cerebral edema. This can be prevented by administration of conivaptan, a safe FDA approved drug that treats euvolemic hyponatremia. Through the process of aquaresis, conivapten which is a vasopressin receptor antagonist improves serum sodium concentration while eliminating free water without having any negative effect on systolic blood pressure and pulse rate.

Due to the differences in users skin colour and thickness most modern pulse watches will include multiple light waves of different lengths to interact with different skin tones and thickness. 2\. Processors - the processor of the pulse watch device will capture the light that is refracted from the user's device and will translate that into a binary code. This code is then transformed into meaningful pulse rate data. 3\. Accelerometer - an accelerometer can measure any motion that is used in combination with the other mentioned components, providing motion and location sensing heart rate data via an algorithm 4\.

The most important initial clue to the diagnosis is one's description of palpitation. The approximate age of the person when first noticed and the circumstances under which they occur are important, as is information about caffeine intake (tea or coffee drinking), and whether continual palpitations can be stopped by deep breathing or changing body positions. It is also very helpful to know how they start and stop (abruptly or not), whether or not they are regular, and approximately how fast the pulse rate is during an attack. If the person has discovered a way of stopping the palpitations, that is also helpful information.

Santorio was the first to use a wind gauge, a water current meter, the pulsilogium (a device used to measure the pulse rate), and a thermoscope. Whereas he invented the former two devices, it is possible that the pulsilogium and thermoscope were inspired by his friend Galileo Galilei, Paolo Sarpi and Giovanni Francesco Sagredo who were his learned circle of friends in Venice. Santorio introduced the pulsilogium at 1602 and thermoscope in 1612. Sanctorio sitting in the balance that he made to calculate his net weight change over time after the intake and excretion of food stuffs and fluids.

Commenting on De pulsibus, he connected the relationship between fast pulse rate and urine output and correlated the color of urine with the condition of the heart. For the originality of his thought Mario Timio suggestedMario Timio, "Gentile da Foligno, a Pioneer of Cardionephrology: Commentary on Carmina de urinarum iudiciis and De pulsibus", American Journal of Nephrology 19 (1999:189-192) (on-line abstract). that Gentile could be indicated as the 'first' cardionephrologist in the history of medicine. He prepared a widely read treatise on the Black Death, recommending theriac among other prophylaxis, but died of the plague himself.

James Mudge from Beyond Hollywood.com gave the film a positive review, writing, "Though The Tunnel nevertheless remains above average and better crafted than most of the never-ending stream of found footage horrors, these missteps prevent it from shaking off the shackles of the form or from finding appeal outside dedicated fans. Still, there’s enough here to make the prospect of a sequel not unpalatable, and despite its faults the film does manage to raise the pulse rate from time to time". In 2014, popular horror movie website Bloody Disgusting listed the film as one of the "13 Scariest Mockumentaries Ever Made".

The cues examined in Project Hostile Intent are those that can be assessed remotely and in real time, like pulse rate, sweating, restless behavior, and possibly brain scans. The procedures and technologies required to collect these cues are non-invasive (like surveillance cameras and body heat sensors) and amenable to integration into busy operational contexts, like airports. In addition to detecting these cues, this project examines whether this process can be automated through the use of sensors and detection algorithms and, subsequently, integrated with other technologies aimed at identifying individuals who pose threats to the U.S.A., e.g.

Today, The Newborn Foundation has documented near universal screening in the United States and international screening is rapidly expanding. In 2014, a third large study of 122,738 newborns that also exclusively used signal extraction technology showed similar, positive results as the first two large studies. High-resolution pulse oximetry (HRPO) has been developed for in-home sleep apnea screening and testing in patients for whom it is impractical to perform polysomnography. It stores and records both pulse rate and SpO2 in 1 second intervals and has been shown in one study to help to detect sleep disordered breathing in surgical patients.

This has made it easier for users to access real-time information in a number of peripheral devices. There are still many future improvements for self-monitoring healthcare devices. Although most of these wearable devices have been excellent at providing direct data to the individual user, the biggest task which remains at hand is how to effectively use this data. Although the blood glucose monitor allows the user to take action based on the results, measurements such as the pulse rate, EKG signals, and calories do not necessarily serve to actively guide an individual's personal healthcare management.

Wrist heart rate monitor Heart rate monitor with a wrist receiver Heart rate is measured by finding the pulse of the heart. This pulse rate can be found at any point on the body where the artery's pulsation is transmitted to the surface by pressuring it with the index and middle fingers; often it is compressed against an underlying structure like bone. The thumb should not be used for measuring another person's heart rate, as its strong pulse may interfere with the correct perception of the target pulse. The radial artery is the easiest to use to check the heart rate.

For aircraft fuel flow meters, K-factor refers to the number of pulses expected for every one volumetric unit of fluid passing through a given flow meter, and is usually encountered when dealing with pulse signals.Calculating and Using K-Factors. Pressure and temperature sensors providing pulses can be used to determine mass flow, with division of the pulses by the K-factor, or multiplication with the inverse of the K-factor providing factored totalization, and rate indication. Furthermore, by dividing the pulse rate by the K-Factor, the volumetric throughput per unit time of the rate of flow can be determined.

An extensive series of tests across the Atlantic were carried out by the USCGC Androscoggin starting in April 1956. Meanwhile, Loran-B proved to have serious problems keeping their transmitters in phase, and that work was abandoned. Minor changes were made to the Cytac systems to further simplify it, including a reduction in the pulse-chain spacing from 1200 to 1000 µs, the pulse rate changed to 20 pps to match the existing Loran-A system, and the phase-shifting between pulses to an alternating 0, 180-degree shift instead of 45 degrees at every pulse within the chain. The result was Loran-C.

In 1925, Bradbury and Eggleston first characterized three patients seemingly with a common syndrome, with what they described as "the occurrence of syncopal attacks after or during exertion or even after standing erect for some minutes. Other features in the three patients are a slow, unchanging pulse rate, incapacity to perspire, a lowered basal metabolism and signs of slight and indefinite changes in the nervous system. Each of these patients felt much worse during the heat of summer." Further research identified multiple causes for these syndromic findings, now grouped as primary autonomic disorders (also called primary dysautonomia), including Pure Autonomic Failure, Multiple System Atrophy, and Parkinson's.

The rotation of the propeller sensors is detected by the magnetodiodes. As a result of the asymmetry in placement of the magnetodiodes, a staggered pair of pulses is produced each quarter revolution; the phase relationship indicates the sense of direction of rotation and the pulse rate indicates the rate of rotation. In order to calculate and record the velocity components, the vector averaging circuitry is turned on by a rotor count, which is signaled by a proper sequence of changes in the levels of the magnetodiodes. The instrument heading ( \theta ) is determined and stored in a register and updated at a 1-Hz rate (once each second).

Metoprolol may worsen the symptoms of heart failure in some patients, who may experience chest pain or discomfort, dilated neck veins, extreme fatigue, irregular breathing, an irregular heartbeat, shortness of breath, swelling of the face, fingers, feet, or lower legs, weight gain, or wheezing. This medicine may cause changes in blood sugar levels or cover up signs of low blood sugar, such as a rapid pulse rate. It also may cause some people to become less alert than they are normally, making it dangerous for them to drive or use machines. Greater care is required with use in those with liver problems or asthma.

This pocket watch made for the medical community has Latin instructions for measuring a patient's pulse rate on its dial: enumeras ad XX pulsus, "you count to 20 beats". Ecclesiastical Latin, the form of New Latin used in the Roman Catholic Church, remained in use throughout the period and after. Until the Second Vatican Council of 1962–65 all priests were expected to have competency in it, and it was studied in Catholic schools. It is today still the official language of the Church, and all Catholic priests of the Latin liturgical rites are required by canon law to have competency in the language.

Oslo, the capital city of Norway, used the New Zealand system, but the rest of the country did not. Systems that used this encoding of the ten digits in a sequence of up to ten pulses, are known as decadic dialing systems. Some switching systems used digit registers that doubled the allowable pulse rate up to twenty pulses per second, and the inter-digital pause could be reduced as the switch selection did not have to be completed during the pause. These included access lines to the Panel switch in the 1920s, Crossbar systems, the later version (7A2) of the Rotary system, and the earlier 1970s stored program control exchanges.

In an article entitled "History of a case in which there took place a remarkable slowness of the pulse", Spens described the case of a previously well man who 'fell to the ground senseless' and 'continued in that state for 5 minutes.' The man's pulse rate was noted to be 24 beats per minute but regular and of normal strength. Several subsequent episodes occurred over the next few days, in some instances accompanied by convulsions and always with a slow regular pulse of normal strength, recorded on one occasion at 10 beats per minute. The patient died after one such episode and no abnormality was found at autopsy.

Unlike an electrostatic ion thruster which uses an electric field to accelerate only one species (positive ions), a PIT uses the Lorentz body force acting upon all charged particles within a quasi-neutral plasma. Unlike most other ion and plasma thrusters, it also requires no electrodes (which are susceptible to erosion) and its power can be scaled up simply by increasing the number of pulses per second. A 1-megawatt system would pulse 200 times per second. Pulsed inductive thrusters can maintain constant specific impulse and thrust efficiency over a wide range of input power levels by adjusting the pulse rate to maintain a constant discharge energy per pulse.

Thus, it was shown by these investigators that intramuscular injections (average effective dose = 200 mg) of the drug produced an increase in systolic blood pressure and pulse rate, without affecting the diastolic pressure. The blood pressure increase reached a maximum (~25 mmHg) in 5 minutes following the injection, then gradually returned to normal over the course of 1 hour. Doses of drug greater than 200 mg caused side-effects such as heart palpitations, headache, sweating, and feelings of apprehension. When given intravenously, doses of 25–50 mg sufficed to produce a mean maximum increase in the blood pressure of 29 mmHg in 2 minutes, and a return to baseline within 30 minutes.

In MFS affected adults, it is recommended they reduce emotional and physical stress and switch from high impact sports such as martial arts, football, basketball etc to isotonic, low impact exercise such as swimming, biking or jogging where the pulse rate lies approximately at <110 beats per minute. Children should also follow similar guidelines to ensure correct management of MFS. MFS is caused by a mutation in the ‘’FBN1’’ gene positioned at chromosome 15q21.1 resulting in a deconstructed form of Fibrillin-1. Fibrillin-1 is a 350-kDa, 2871-amino acid cystine-rich glycoprotein that is responsible for the amalgamation of elastin into the elastic fibres of the connective tissue in the extracellular matrix (ECM).

It may not be appropriate, or indeed even possible, to stop the test before fainting occurs, as the drop in blood pressure or pulse rate associated with fainting can come on in seconds. This is why the patient's blood pressure and ECG should be continuously monitored during the test. If at any time in tilt table testing a patient loses consciousness, he or she will be returned to a supine or head down position and will be given immediate medical attention, which could include being given fluids or perhaps atropine or a sympathomimetic drug like epinephrine or ephedrine which will raise blood pressure and heart rate rapidly. In extreme cases, tilt table testing could provoke seizures or even cause the heart to stop.

During this smoking ban, Dr. Benjamin Weybrew carried out a battery of tests on crew volunteers, both smokers and non-smokers, to measure cardiovascular functions and psychological stress indices to determine the effects that the prohibition of tobacco had on individual and group performance of the test subjects. The objective of this experiment was to determine the advisability of prohibiting the use of tobacco from submarine operations given the extended submerged duration of missions involving nuclear-powered submarines.Weybrew. The ABC's of Stress. pp. 88–89. The test results determined that smokers showed consistently higher mean oral temperature and pulse rate, both at rest and following exercises, as well as significantly increased pulse rates over non-smokers, a marked decrease in alertness, and an increase in insomnia symptoms.

The link spectral efficiency of a digital communication system is measured in bit/s/Hz, or, less frequently but unambiguously, in (bit/s)/Hz. It is the net bitrate (useful information rate excluding error-correcting codes) or maximum throughput divided by the bandwidth in hertz of a communication channel or a data link. Alternatively, the spectral efficiency may be measured in bit/symbol, which is equivalent to bits per channel use (bpcu), implying that the net bit rate is divided by the symbol rate (modulation rate) or line code pulse rate. Link spectral efficiency is typically used to analyse the efficiency of a digital modulation method or line code, sometimes in combination with a forward error correction (FEC) code and other physical layer overhead.

The data on which the Shannon model was built are restricted to experiments performed in cat cerebral cortex with 7 hours of stimulation under light anesthesia at 50 pps with 400 µs pulses (charge- balanced, symmetric, biphasic, anodic-first) using platinum surface disc electrodes of 1 mm² or larger, recessed, anodized sintered tantalum-tantalum pentoxide pellet electrodes of 1 mm in diameter, or iridium penetrating microelectrodes of 6500 µm². As a result of these restricted methods, Shannon states "A more comprehensive model of safe levels for electrical stimulation would also account for the effects of pulse rate, pulse duration, stimulus duty cycle, and duration of exposure." Additionally, further study has demonstrated that microelectrodes do not obey the Shannon criterion, and new approaches may be proposed to address these limitations.

Some communication links (such as GPS transmissions, CDMA cell phones, and other spread spectrum links) have a symbol rate much higher than the data rate (they transmit many symbols called chips per data bit). Representing one bit by a chip sequence of many symbols overcomes co-channel interference from other transmitters sharing the same frequency channel, including radio jamming, and is common in military radio and cell phones. Despite the fact that using more bandwidth to carry the same bit rate gives low channel spectral efficiency in (bit/s)/Hz, it allows many simultaneous users, which results in high system spectral efficiency in (bit/s)/Hz per unit of area. In these systems, the symbol rate of the physically transmitted high-frequency signal rate is called chip rate, which also is the pulse rate of the equivalent base band signal.

In January 2019, biologists Alexander L. Stubbs of the University of California, Berkeley and Fernando Montealegre-Z of the University of Lincoln analyzed a recording of a sound made by US personnel in Cuba and release to the Associated Press. Stubbs and Montealegre-Z concluded that the sound was caused by the calling song of the Indies short-tailed cricket (Anurogryllus celerinictus) rather than a technological device. Stubbs and Montealegre-Z matched the song's "pulse repetition rate, power spectrum, pulse rate stability, and oscillations per pulse" to the recording. Stubbs and Montealegre wrote that "Although the causes of the health problems reported by embassy personnel are beyond the scope of this paper and called for "more rigorous research into the source of these ailments, including the potential psychogenic effects, as well as possible physiological explanations unrelated to sonic attacks.

The other technique that helps the ASTAMIDS successfully detect minefields and road side bombs uses a combination of the tactical synthetic aperture radar ability to penetrate the ground and a group of multi-spectral electro-optical sensors that cover the visible and near-infrared (VNIR) and mid-wave infrared (MWIR) portions of the spectrum, as well as a target laser rangefinder and designator. Once an IED is found using the change detection method, the laser rangefinder and designator flashes to the point where the change was detected. A seeker is then used to find the lasers pulse rate and guides the EO / IR sensors of the ASTAMIDS to the point. Now that the sensors know what point to scan, the mission specific hardware, software, and firmware components installed in the ASTAMIDS can successfully detect mines buried under the surface.

This theory postulates that activation of large diameter, myelinated primary afferent fibers suppresses the response of dorsal horn neurons to input from small, unmyelinated primary afferents. A simple SCS system consists of three different parts. First, microelectrodes are implanted in the epidural space to deliver stimulation pulses to the tissue. Second, an electrical pulse generator implanted in the lower abdominal area or gluteal region while is connected to the electrodes via wires, and third a remote control to adjust the stimulus parameters such as pulse width and pulse rate in the PG. Improvements have been made in both the clinical aspects of SCS such as transition from subdural placement of contacts to epidural placement, which reduces the risk and morbidity of SCS implantation, and also technical aspects of SCS such as improving percutaneous leads, and fully implantable multi-channel stimulators.

The criteria to define a patient as stable or unstable could have variations from institution to institution. For example, Burack et al. used a list of 6 criteria in his paper that defined an unstable hemodynamic state: # Traumatic cardiac arrest or near arrest and an EDT # Cardiac tamponade # Persistent ATLS class III shock despite fluid resuscitation (blood loss 1500–2000 mL, pulse rate greater than 120, blood pressure decreased) # Chest tube output greater than 1500 mL of blood on insertion # Chest tube output greater than 500 mL/hour for the initial hour # Massive hemothorax after chest tube drainage One common criteria found in literature is a sustained systolic blood pressure of less than 100 mmHg, but this can be an oversimplification. Patients with clinical evidence of possible TMGSW that are considered unstable receive no further evaluation and are taken to surgery immediately.

Because the hammers are made of white lead, the instrument sheds small amounts of lead powder. Musicians who actively use this instrument have adopted the practice of coating the hammers in Epoxy glue, which does not affect the sound but stops the wearing away of the hammers (and prevents the poisoning of children, cats and other small creatures). In addition to being limited to the keys of C major and A minor (and modal variants), the Marxophone is partially limited to certain tempos because of the rate at which the hammers bounce on the strings. The fixed pulse rate of the hammer strike fits the music best when it is a power-of-two denominated fraction of the pulse of the music, in other words an 8th, 16th, 32nd, or 64th note of the performance tempo.

By taking information per pulse in bit/pulse to be the base-2-logarithm of the number of distinct messages M that could be sent, Hartley constructed a measure of the line rate R as: : R = f_p \log_2(M), where f_p is the pulse rate, also known as the symbol rate, in symbols/second or baud. Hartley then combined the above quantification with Nyquist's observation that the number of independent pulses that could be put through a channel of bandwidth B hertz was 2B pulses per second, to arrive at his quantitative measure for achievable line rate. Hartley's law is sometimes quoted as just a proportionality between the analog bandwidth, B, in Hertz and what today is called the digital bandwidth, R, in bit/s. Other times it is quoted in this more quantitative form, as an achievable line rate of R bits per second: : R \le 2B \log_2(M).

Kralj's approach was extended by Graupe et al. into a digital FES system that employs the power of digital signal processing to result in the Parastep FES system, based on US Patents 5,014,705 (1991), 5,016,636 (1991), 5,070,873 (1991), 5,081,989 (1992), 5,092,329 (1992) and related foreign patents. The Parastep system became the first FES system for standing and walking to receive the US FDA approval (FDA, PMA P900038, 1994) and become commercially available. The Parastep's digital design allows a considerable reduction in rate of patient-fatigue by drastically reducing of stimulation pulse-width (100–140 microseconds) and pulse-rate (12–24 per sec.), to result, in walking times of 20–60 minutes and average walking distances of 450 meters per walk, for adequately trained thoracic-level complete paraplegics patients who complete training that includes daily treadmill sessions, with some patients exceeding one mile per walk.
