Heated humidified high-flow (HHHF) therapy, often also high flow nasal cannula(e) (HFNC) or high flow nasal oxygen (HFNO), is a type of respiratory support method that delivers a high flow (liters per minute) of medical gas to a patient through an interface (nasal cannulae) intended to create a wash-out of the upper airway. The applied gas is heated to best match human body temperature (37 °C) and humidified targeting ideal body saturation vapor pressure. It is used in acute and chronic breathing problems, and is a suitable choice for treatment of patients with severe or critical COVID-19.Geng, Shike, Mei, Qing, Zhu, Chunyan, et al.

Coon's patent claimed: # A process for ripening cheese, consisting of supplying, through suitable means, humidified air to a room or chamber set aside for the purpose, the humidified air to have a range of temperature from 45° to 75° F., and a moisture percentage of from 65% to 95%. # A process for ripening cheese having an original moisture percentage of 36% to 40% and subjecting it to a temperature of 55° F., to 70° F., in combination with a humidity percentage of from 75% to 90%. From 1933, a cheese was marketed by Fred Walker as Red Coon, and was coated with red wax. The wax was later replaced with cellophane, and the red stripe in the logo is a residual reference to the original packaging.

Potatoes that are stored in artificially humidified warehouses contain more water, which makes the time required to deep fry them into chips longer. This increases the carbon dioxide footprint of commercially producing chips because more energy is required for frying over a longer time. According to one source, an average home appliance deep fryer draws 2,000 watts.

This is probably caused by the release of prostaglandins. The underlying cause of this type of bronchoconstriction appear to be the large volume of cool, dry air inhaled during strenuous exercise. The condition appears to improve when the air inhaled is more fully humidified and closer to body temperature. This specific condition, in the general population, can vary between 7 and 20 percent.

Air is warmed to , humidified and cleansed by the conducting zone. Particles from the air being removed by the cilia on the respiratory epithelium lining the passageways, in a process called mucociliary clearance. Pulmonary stretch receptors in the smooth muscle of the airways initiate a reflex known as the Hering–Breuer reflex that prevents the lungs from over-inflation, during forceful inspiration.

Treatment aims to prevent respiratory failure and to ensure adequate blood oxygenation. Supplemental oxygen can be given and it may be warmed and humidified. When the contusion does not respond to other treatments, extracorporeal membranous oxygenation may be used, pumping blood from the body into a machine that oxygenates it and removes carbon dioxide prior to pumping it back in.

Leslie William Peterson also made significant contributions to the improvement of the tracheostome. In 2006, his tracheal tube/catheter adaptor cap was introduced and consisted in a cap with two separate projections that allowed the catheter to be in position and prevent their rotation. It also provided heated and/or humidified gas to patients dependent on the breathing machine.[Peterson, Leslie. 2006.

The bubble CPAP system consists of three major components: 1\. Gas source: An oxygen blender connected to a source of oxygen and compressed air is used to supply an appropriate concentration of inspired oxygen (FiO2). The humidified blended oxygen is then circulated through corrugated tubing. 2\. Pressure generator: Pressure in the bubble CPAP system is created by placing the distal expiratory tubing in water.

This can lead to hypothermia and dehydration. Strategies to prevent these problems are the use of emollients or nursing the baby in a humidified incubator. There is also an increased risk of skin infection and mechanical compression, leading to problems like limb ischemia. There is also a risk of intoxication by cutaneous absorption of topical products, for example salicylate intoxication (similar to aspirin overdose) due to keratolytics.

Anti-bacterial soap is not recommended by sellers. To reduce the risk of contamination, distilled water is a good alternative to tap water. If traveling in areas where the mineral content or purity of the water is unknown or suspect, an alternative is to use a water "purifier" such as Brita. In cold climates, humidified air may require insulated and/or heated air hoses.

The documents were thoroughly examined for signs of deterioration and past restorations, all of which were thoroughly documented in condition reports. The first step of treatment stabilized the ink of the text using a gelatin adhesive. The dirt and grime were then cleaned from the parchments, though original intentional marks were left alone. The Constitution and the Bill of Rights were then humidified and dried under tension to flatten the parchments.

Risks and complications of minimally invasive procedures are the same as for any other surgical operation, among the risks are: death, bleeding, infection, organ injury, and thromboembolic disease There may be an increased risk of hypothermia and peritoneal trauma due to increased exposure to cold, dry gases during insufflation. The use of surgical humidification therapy, which is the use of heated and humidified CO2 for insufflation, may reduce this risk.

Hadrurus spadix can be housed in a big vivarium. A mixture of peat and sand should be used for substrate, though sand should be the major component. The substrate should be humidified in order to stabilize it and permit burrowing, then dried before introducing the scorpion in the vivarium. A rock or a piece of bark should be provided so the scorpion can dig its burrow under it.

ATDA is compatible with silicone oil or pluronic additives, such as F-68, which reduce non-specific absorption and biofouling when dealing with biological fluids such as proteins, biological serums, and DNA. A drawback of a setup like this is accelerated droplet evaporation. ATDA is a form of open digital microfluidics, and as such the device needs to be encapsulated in a humidified environment in order to minimize droplet evaporation.

One solution to this problem involves growing cells on an MEA inside a sealed chamber. This chamber serves as a non-humidified incubator that is enclosed by a fluorinated ethylene propylene (FEP) membrane that is permeable to select gases (i.e. gases necessary for metabolism) but impermeable to water and microbes. Other solutions entail an incubator with an impermeable membrane that has a specific mix of gases (air with 5% CO2 is typical) sealed inside.

Humidification is a parchment conservation treatment which involves the controlled and monitored increase in relative humidity. Humidified parchments are more flexible, which will allow for corrections to distortions like cockling, puckering and changes in original size. Some methods of humidification are: humidification chambers: moisture chambers with ultrasonic humidifier, moisture chambers with steam/ultrasonic mist; and application of alcohol and water. Localized humidification is sometimes used to treat specific folds or creases in parchment objects.

The Declaration of Independence, which has been damaged by frequent handling and exposure, was not humidified because of its increased moisture sensitivity. All the parchments were then installed into new titanium and aluminum encasements, developed by the National Institute of Standards and Technology, which are filled with inert argon gas. The current environmental conditions of the Charters of Freedom encasements is monitored by scientists and conservators for signs of possible deterioration agents.

The earliest, and most widely used form of adult nasal cannula carries 1–3 litres of oxygen per minute. Cannulae with smaller prongs intended for infant or neonatal use can carry less than one litre per minute. Flow rates of up to 60 litres of air/oxygen per minute can be delivered through wider bore humidified nasal cannula. The nasal cannula was invented by Wilfred Jones and patented in 1949 by his employer, BOC.

Many species, however, require additional humidification to survive indoors. As with lighting, some humidification solutions can be integrated into the regular living area and some require a dedicated space. Local humidity can be raised by locating the bonsai containers over a tray of water, or by placing them in a bed of dampened sand. For better effect, the bonsai can be placed in enclosures, such as terrariums, that are humidified from within.

The gas was humidified and the pressure increased to get better mileage. The movie states that Shell Oil bought this idea and asked if they buried it. In 1977 the book Fuel Economy of the Gas Engine by Shell scientists states that they got 150 mpg in a 1947 Studebaker. On May 1, 1977, The El Paso Times ran a front page article with the headline "200 Miles on 2 Gallons of Gas".

In food packaging, inert gases are used as a passive preservative, in contrast to active preservatives like sodium benzoate (an antimicrobial) or BHT (an antioxidant). Historical documents may also be stored under an inert gas to avoid degradation. For example, the original documents of the U.S. Constitution are stored under humidified argon. Helium was previously used, but it was less suitable because it diffuses out of the case more quickly than argon.

Storage can be diurnal, weekly, monthly, or even seasonal depending on the volume of the zeolite and the area of the solar thermal panels. When heat is called for during the night, or sunless hours, or winter, humidified air flows through the zeolite. As the humidity is adsorbed by the zeolite, heat is released to the air and subsequently to the building space. This form of TES, with specific use of zeolites, was first taught by Guerra in 1978.

To prepare the fiber, the leaves are opened and dried in the sun, then bleached using sulfur. It is important to work the fiber while moist so that it does not break with the manipulation. During the rainy season, the work is done outdoors but during the dry season, artisans have special humidified rooms, caves and basements for this purpose. The weaving begins in the center of the top of the head and ends at the brim.

As of 2017 heated and humidified air, such as via RhinoTherm, is of unclear benefit. One study has found chest vapor rub to provide some relief of nocturnal cough, congestion, and sleep difficulty. Some advise to avoid physical exercise if there are symptoms such as fever, widespread muscle aches or fatigue. It is regarded as safe to perform moderate exercise if the symptoms are confined to the head, including runny nose, nasal congestion, sneezing, or a minor sore throat.

L. cherrii and other Legionella species are considered to be intracellular bacteria that can cause major respiratory problems in humans. Infection occurs when a human host inhales the organism, which may be carried in humidified air. Distinguishing patients with Legionnaire’s disease is difficult because most are asymptomatic due to Legionnaire’s disease being similar to other types of pneumonia. Although L. pneumophila is the leading cause of Legionnaire’s disease, other Legionella species (such as L. cherrii) likely are capable of causing this disease.

Also, the use of humidified, heated, high-flow nasal cannula may be a safe initial therapy to decrease work of breathing and need for intubation. However, evidence is lacking regarding the use of high-flow nasal cannula compared to standard oxygen therapy or continuous positive airway pressure. These practices may still be used in severe cases prior to intubation. Blood gas testing is not recommended for people hospitalized with the disease and is not useful in the routine management of bronchiolitis.

After the surgery, some patients require intubation and mechanical ventilation for several days to allow adequate tracheal toilet, but most patients can have the tubes removed soon after the surgery. The obstructive airway symptoms may be worse in the first postoperative weeks. Only a few patients have immediate relief of stridor, but many obtain immediate relief of problems with swallowing (dysphagia). After extubation, it might be necessary to maintain positive airway pressure by appropriate flows of a humidified oxygen/air mixture.

If a house is artificially humidified during the winter, this can create conditions favorable to mold. Moving air may prevent mold from growing, since it has the same desiccating effect as low humidity. Mold grow best in warm temperatures, , although growth may occur between . Removing one of the three requirements for mold reduces (or eliminates) new mold growth: moisture; food for the mold spores (for example, dust or dander); and warmth since mold generally does not grow in cold environments.

"Clay layers" are dry clay (Vcl) which also form part of the grain volume. If a core sample is dried in a normal dry oven (non-humidified atmosphere) the clay layers and quartz together form the grain volume, with all other components constituting core analysis “total porosity” (notwithstanding comments in ). This core total porosity will generally be equivalent to the total porosity derived from the density log when representative values for matrix and fluid density are used. The clay layers contain groups (often termed “structural water”).

Not to be confused with undercut, fret over binding. As the decades pass the aged fingerboard wood reaches its natural equilibrium and fret sprouts on Victory MV's have become extremely rare when properly humidified. By comparison, If you read guitar forums, you will find many brand new kiln-dried beginner level guitars have major shrinkage problems with fret sprout causing the guitar to be uncomfortable or even unplayable. The fret board on Victory Mv's have Nacre inlay markers, also known as mother of pearl, or oyster shell.

It carries winds that have already lost their moisture out to the ocean (opposite from the summer monsoon). They cross India diagonally from northeast to southwest. However, the large indentation made by the Bay of Bengal into India's eastern coast means that the flows are humidified before reaching Cape Comorin and rest of Tamil Nadu, meaning that the state, and also some parts of Kerala, experience significant precipitation in the post-monsoon and winter periods. However, parts of West Bengal, Orissa, Andhra Pradesh, Karnataka and Mumbai also receive minor precipitation from the north-east monsoon.

Plummer worked closely with Frederic Maass, of Maass & McAndrew, to design and fabricate many of the building systems innovations like the steam sterilization rooms, metal surgical tools and equipment, pneumatic tube system, knee operated sinks, and a state of the art HVAC system. The air exchange rate for the building was three minutes. One intriguing innovation was the Rookwood fountain in the main lobby that was designed to clean and humidify air from the outside. It also heated and humidified air in the winter, and provided cool air in the summer.

While the potential triggering events for E.I.B. are well recognized, the underlying pathogenesis is poorly understood. It usually occurs after at least several minutes of vigorous, aerobic activity, which increases oxygen demand to the point where breathing through the nose (nasal breathing) must be supplemented by mouth breathing. The resultant inhalation of air that has not been warmed and humidified by the nasal passages seems to generate increased blood flow to the linings of the bronchial tree, resulting in edema. Constriction of these small airways then follows, worsening the degree of obstruction to airflow.

Robert Nunnemacher (April 7, 1854 – March 8, 1912) was a member of one of Milwaukee's pioneer families of Swiss origin. In the 1890s through the turn of the century, Mr. Nunnemacher was among the twenty most successful and wealthiest businessmen in America, expanding on his father's (Jacob Nunnemacher) business empire and joined by the likes of Andrew Carnegie and John D. Rockefeller. Robert Nunnemacher is best known for the system of malting drum he developed. It involved a rotating drum and humidified air between a central duct, and other periphery ducts to condition germinating grain.

The two nasal cavities condition the air to be received by the other areas of the respiratory tract. Owing to the large surface area provided by the nasal conchae (also known as turbinates), the air passing through the nasal cavity is warmed or cooled to within 1 degree of body temperature. In addition, the air is humidified, and dust and other particulate matter is removed by nasal hair in the nostrils. The entire mucosa of the nasal cavity is covered by a blanket of mucus, which lies superficial to the microscopic cilia and also filters inspired air.

Delivery of High Fi. Cardinal Health Respiratory Abstracts. Another type of device is a humidified high flow nasal cannula which enables flows exceeding a person's peak inspiratory flow demand to be delivered via nasal cannula, thus providing FIO2 of up to 100% because there is no entrainment of room air, even with the mouth open.Accurate Oxygen Delivery This also allows the person to continue to talk, eat and drink while still receiving the therapy. This type of delivery method is associated with greater overall comfort, and improved oxygenation and respiratory rates than with face mask oxygen.

The peat up to about from the surface is mainly humidified S. acutifolia, with fresher S. imbricatum peat nearer the surface. A area of Chat Moss, to the north of the Liverpool–Manchester railway line, notified as Astley & Bedford Mosses, was designated a Site of Special Scientific Interest in 1989. Astley & Bedford Mosses, along with Risley Moss and Holcroft Moss, is also a European Union designated Special Area of Conservation, known as Manchester Mosses. The major habitats in the moss are bog, heathland, woodland and acidic grassland, subject to varying degrees of wetness depending on the local drainage.

Here, the embryo is grown outside of the shell. In this method, the eggs are first kept in inside a humidified incubator for up to a period of 3 days, to ensure that the position of the embryo is opposite to the position where the egg will be subsequently cracked. A small hole is made on the side of the air chamber to equilibrate the pressure, followed by the cracking of the egg on a petri-dish. This method is ideal for visualizing the growing embryo and their manipulation without limitations in accessing the embryo during the different stages of development.

The delicate instruments were kept at the group controls in an air conditioned and de- humidified storage room and only issued to posts during Transition To War. Once at the posts the instrument was unpacked from its wooden transit case and prepared for use. If radiation readings approached the 400 roentgen level the telescopic rod was quickly collapsed and the probe reinserted to a distance below the surface that reduced the dial reading by a factor of ten. Thus the instrument became capable of producing accurate readings to a level of 5,000 roentgens per hour external reading.

Heated humidification of respiratory gases during surgery has been demonstrated to reduce the fall in core body temperature, especially in surgeries lasting longer than one hour. The lungs can be insufflated with respiratory gases that are heated to near body temperature and humidified to 90 to 100% relative humidity(RH). Normally, air in the lungs is at core body temperature and at close to 100% RH. Especially when cold dry gases (such as anhydrous compressed gas from oxygen tanks) are used, it cool and can dry the airway. The body then utilizes energy to evaporate sufficient water from the lungs to maintain lung gas temperature and humidity.

Realizing that air conditioning would one day be a standard feature of private homes, particularly in regions with warmer climate, David St. Pierre DuBose (1898-1994) designed a network of ductwork and vents for his home Meadowmont, all disguised behind intricate and attractive Georgian-style open moldings. This building is believed to be one of the first private homes in the United States equipped for central air conditioning. In 1945, Robert Sherman of Lynn, Massachusetts invented a portable, in-window air conditioner that cooled, heated, humidified, dehumidified, and filtered the air. By the late 1960s, most newly built residential homes in the United States had central air conditioning.

If the ambient pressure reduction is limited, this desaturation will take place in the dissolved phase, but if the ambient pressure is lowered sufficiently, bubbles may form and grow, both in blood and other supersaturated tissues. When the partial pressure of all gas dissolved in a tissue exceeds the total ambient pressure on the tissue it is supersaturated, and there is a possibility of bubble formation. The sum of partial pressures of the gas that the diver breathes must necessarily balance with the sum of partial pressures in the lung gas. In the alveoli the gas has been humidified and has gained carbon dioxide from the venous blood.

During inhalation, environmental air initially enters the bird through the nostrils from where it is heated, humidified, and filtered in the nasal passages and upper parts of the trachea. From there, the air enters the lower trachea and continues to just beyond the syrinx, at which point the trachea branches into two primary bronchi, going to the two lungs. The primary bronchi enter the lungs to become the intrapulmonary bronchi, which give off a set of parallel branches called ventrobronchi and, a little further on, an equivalent set of dorsobronchi. The ends of the intrapulmonary bronchi discharge air into the posterior air sacs at the caudal end of the bird.

The gas is then heated, generally to about 37 °C, and humidified to near 100% RH using a humidifier. The gas is transported to the patient through a heated delivery tube to prevent cooling and condensation of the water vapor that has been added to the respiratory gas(es). HFT requires the use of nasal cannulae and a system designed to deliver high flow rates and the pressure generated to do so. At the same time the nasal cannula must be small enough that they do not occlude more than 50% of the nares, as this allows flow to have multiple points of exit for a continuous airway flush effect.

Bubble CPAP is a non-invasive ventilation strategy for newborns with infant respiratory distress syndrome (IRDS). It is one of the methods by which continuous positive airway pressure (CPAP) is delivered to a spontaneously breathing newborn to maintain lung volumes during expiration. With this method, blended and humidified oxygen is delivered via short binasal prongs or a nasal mask and pressure in the circuit is maintained by immersing the distal end of the expiratory tubing in water. The depth to which the tubing is immersed underwater determines the pressure generated in the airways of the infant. As the gas flows through the system, it “bubbles” out and prevents buildup of excess pressures.

A seawater greenhouse is a greenhouse structure that enables the growth of crops in arid regions, using seawater and solar energy. The technique involves pumping seawater (or allowing it to gravitate if below sea level) to an arid location and then subjecting it to two processes: first, it is used to humidify and cool the air, and second, it is evaporated by solar heating and distilled to produce fresh water. Finally, the remaining humidified air is expelled from the greenhouse and used to improve growing conditions for outdoor plants. The technology was introduced by British inventor Charlie Paton in the early 1990s and is being developed by his UK company Seawater Greenhouse Ltd.

An airliner fuselage, such as this Boeing 737, forms a cylindrical pressure vessel Cabin pressurization is a process in which conditioned air is pumped into the cabin of an aircraft or spacecraft, in order to create a safe and comfortable environment for passengers and crew flying at high altitudes. For aircraft, this air is usually bled off from the gas turbine engines at the compressor stage, and for spacecraft, it is carried in high-pressure, often cryogenic tanks. The air is cooled, humidified, and mixed with recirculated air if necessary, before it is distributed to the cabin by one or more environmental control systems. The cabin pressure is regulated by the outflow valve.

|
There is a metabolic reduction of total gas pressure in the tissues. The sum of partial pressures of the gas that the diver breathes must necessarily balance with the sum of partial pressures in the lung gas. In the alveoli the gas has been humidified by a partial pressure of approximately 63 mbar (47 mmHg) and has gained about 55 mbar (41 mmHg) carbon dioxide from the venous blood. Oxygen has also diffused into the arterial blood, reducing the partial pressure of oxygen in the alveoli by about 67 mbar(50 mmHg) As the total pressure in the alveoli must balance with the ambient pressure, this dilution results in an effective partial pressure of nitrogen of about 758 mb (569 mmHg) in air at normal atmospheric pressure.

It is suggested that the origins of the Haratin can be traced back to the original black African (and later also mixed-race) inhabitants of the Tassili n'Ajjer and Acacus Mountains sites in the Epipalaeolithic era. In the Neolithic era when the climate humidified, the ancestors of the Haratin were mostly hunters and ox-herders. At the end of the second millennium before common era and with the introduction of the horse, Proto-Berbers from Northeastern Africa started to conquer the Western part of the Sahara and largely displaced the earlier peoples. When the Sahara dried up some natives moved to the Sahel for a more humid climate while others, the ancestors of the Haratin stayed around the oases across the Sahara, such as the Draa valley region, where they have lived for centuries.

The topographic position of the Caspian lowlands results in a very characteristic Hyrcanian climate, and the whole province of Gilan belongs to this exceptionally humid and green area. Prevailing north-south atmospheric currents, humidified over the Caspian, are forced to a vigorous ascendancy by the mighty barrier of Alborz and thus pour all around the year abundant rainfall on both the plain and the north-western slope of the mountains. The precipitation regime shows a sharp maximum in autumn (September to December), when atmospheric instability is at its highest point, medium values in winter and early spring, and lowest values from May to August. Mean annual rainfall varies between 1200 and 1800 mm along the shoreline, decreases towards a sub-humid area in the south-western corner of the, and reaches again very high amounts in the lower part of the mountain, up to 1500–1800 m.
