The Hagen–Poiseuille equation is useful in determining the vascular resistance and hence flow rate of intravenous fluids that may be achieved using various sizes of peripheral and central cannulas. The equation states that flow rate is proportional to the radius to the fourth power, meaning that a small increase in the internal diameter of the cannula yields a significant increase in flow rate of IV fluids. The radius of IV cannulas is typically measured in "gauge", which is inversely proportional to the radius. Peripheral IV cannulas are typically available as (from large to small) 14G, 16G, 18G, 20G, 22G.

Only small blunt cannulas are used, great care is used to not injure lymphatic which are already abnormal and increased risk of injury. Only the longitudinal orientation of cannulas is used at critical junctures. Preoperatively critical lymphatic structures are scanned and marked. FLLA surgery is significantly more time-consuming than cosmetic surgery often requiring 4-5 hours per body part; much larger aspirate volume is removed versus cosmetic suction lipectomy.

A cannula is used in an emergency procedure to relieve pressure and bloating in cattle and sheep with ruminal tympany, due most commonly to their accidentally grazing wilted legume or legume-dominant pastures, particularly alfalfa, ladino, and red and white clover.Diseases of the Ruminant Forestomach : Bloat, Merck Veterinary Manual Cannulas are a component used in the insertion of the Verichip. Much larger cannulas are used to research about the digestive system of cows.

Trocar, c. 1850. Originally, doctors used trocars to relieve pressure build-up of fluids (edema) or gases (bloating). Patents for trocars appeared early in the 19th century, although their use dated back possibly thousands of years. By the middle of the 19th century, trocar-cannulas had become sophisticated, such as Reginald Southey's invention of the Southey tube.

This does not address a particular technique but the diameter of the cannula, a stainless steel tube which is inserted into subcutaneous fat through a small opening or incision in the skin. The outside diameter of micro-cannulas range from 1 mm to 3 mm.Wollina, Uwe & Goldman, Alberto & Heinig, Birgit. (2010). Microcannular tumescent liposuction in advanced lipedema and Dercum's disease.

The insertion of a plastic cannula and withdrawal of the needle was introduced as a technique in 1945. The first disposable version to be marketed was the Angiocath, first sold in 1964. In the 1970s and 1980s, the use of plastic cannulas became routine, and their insertion was more frequently delegated to nursing staff. Newer catheters have been equipped with additional safety features to avoid needlestick injuries.

The suggested frequency for this condition in the general population is around 0.11%. The hair loss is non-progressive and does not expand beyond these areas. It is a non-inflammatory, non-scarring form of hair loss easily confused with alopecia areata. In one report, the condition was incorrectly believed by the parents to be induced by doctors inserting intravenous cannulas into scalp vessels during the neonatal period.

Bronchoconstriction occurred due to constriction of smooth muscle and airway wall thickening due to peribronchial edema. This peribronchial edema is likely caused by impairment of left ventricular relaxation, elevating microvascular hydrostatic pressure. Proving this theory of edema, during investigation, abundant and frothy fluid was found in tracheal cannulas after sarafotoxin injection. The same study also found marked disturbances in gas exchange and acid-base equilibrium after injection with the toxin.

A cannula A cannula (; from Latin "little reed"; plural cannulae or cannulas)cannula Oxford Dictionaries. Retrieved: 2014-09-18. is a tube that can be inserted into the body, often for the delivery or removal of fluid or for the gathering of samples. In simple terms, a cannula can surround the inner or outer surfaces of a trocar needle thus extending the effective needle length by at least half the length of the original needle.

If two cannula are required (single-stage cannulation), the first one is typically passed through the superior vena cava and the second through the inferior vena cava. The femoral vein may also be cannulated in select patients. If the heart must be stopped for the operation, cardioplegia cannulas are also required. Antegrade cardiopledgia (forward flowing, through the heart's arteries), retrograde cardiopledgia (backwards flowing, through the heart's veins), or both types may be used depending on the operation and surgeon preference.

Oxygen therapy is used to treat emphysema, pneumonia, some heart disorders (congestive heart failure), some disorders that cause increased pulmonary artery pressure, and any disease that impairs the body's ability to take up and use gaseous oxygen.Cook & Lauer 1968, p.510 Treatments are flexible enough to be used in hospitals, the patient's home, or increasingly by portable devices. Oxygen tents were once commonly used in oxygen supplementation, but have since been replaced mostly by the use of oxygen masks or nasal cannulas.

Net, February 26, 2019. and first published in Annales de Chirurgie Plastique in 1984, was a "wet method" using blunt cannulas, rather than sharp, and of smaller size than previously, in order to minimise bleeding while injecting saline solution into the subcutaneous fat deposits, breaking up the fat for extraction by suction.Elisa Bellini, Michele P. Grieco and Edoardo Raposio, "A journey through liposuction and liposculture: Review", Annals of Medicine Surgery 24, December 2017, 53–60, . He referred to his method of aspiration as "collassoplasty".

In cases that do not involve shock, the patient is generally administered a proton pump inhibitor (e.g. omeprazole), given blood transfusions (if the level of hemoglobin is extremely low, that is less than 8.0 g/dL or 4.5–5.0 mmol/L), and kept NPO, which stands for "nil per os" (Latin for "nothing by mouth", or no eating or drinking) until endoscopy can be arranged. Adequate venous access (large-bore cannulas or a central venous catheter) is generally obtained in case the patient suffers a further bleed and becomes unstable.

In the United States, the typical lethal injection begins with the condemned person being strapped onto a gurney; two intravenous cannulas ("IVs") are then inserted, one in each arm. Only one is necessary to carry out the execution; the other is reserved as a backup in the event the primary line fails. A line leading from the IV line in an adjacent room is attached to the prisoner's IV and secured so that the line does not snap during the injections. The arm of the condemned person is swabbed with alcohol before the cannula is inserted.

Urokinase is effective for the restoration of flow to intravenous catheters blocked by clotted blood or fibrin (catheter clearance). Catheters are used extensively to administer treatments to patients for such purposes as dialysis, nutrition, antibiotic treatment and cancer treatment. Approximately 25% of catheters become blocked, meaning that affected patients cannot receive treatment until the catheter has been cleared or replaced. Urokinase is also used clinically as a thrombolytic agent in the treatment of severe or massive deep venous thrombosis, peripheral arterial occlusive disease, pulmonary embolism, acute myocardial infarction (AMI, heart attack), and occluded dialysis cannulas (catheter clearance).

Efficiency illustration of the different radiation technologies (electron beam, X-ray, gamma rays) The safety of irradiation facilities is regulated by the United Nations International Atomic Energy Agency and monitored by the different national Nuclear Regulatory Commissions (NRC). The radiation exposure accidents that have occurred in the past are documented by the agency and thoroughly analyzed to determine the cause and improvement potential. Such improvements are then mandated to retrofit existing facilities and future design. Gamma radiation is very penetrating, and is commonly used for sterilization of disposable medical equipment, such as syringes, needles, cannulas and IV sets, and food.

In medical field, "lost" tubes are tubes which have to be replaced after single use. This is not genuine tube cleaning in the proper sense and is very often applied in the medical sector, for instance with cannulas of syringes, infusion needles or medical appliances, such as kidney machines at dialysis. The reasons for the single use are primarily the elimination of infection risks but also the fact that cleaning would be very expensive and, particularly with cheap mass products, out of all proportion in terms of cost. Single use is therefore common practice with tubes of up to 20 mm diameter.

At this point, the patient is ready to go on bypass. Blood from the venous cannula(s) enters the CPB machine by gravity where it is oxygenated and cooled (if necessary) before returning to the body through the arterial cannula. Cardiopledgia can now be administered to stop the heart, and a cross-clamp is placed across the aorta between the arterial cannula and cardiopledgia cannula to prevent the arterial blood from flowing backwards into the heart. Once the patient is ready to come off of bypass support, the cross-clamp and cannulas are removed and protamine sulfate is administered to reverse the anticoagulative effects of heparin.

Standard equipment on each ambulance includes some of the following: a Life Pak LP 15/ Zoll M Series cardiac monitor; epinephrine auto-injectors (Epi-Pen); oxygen administered via nasal cannulas; non rebreathing masks and bag valve masks; various length splints; stairchair; oral glucose; sterile gauze bandages and medical tape; blood pressure cuffs; oral suction device. Various immobilization equipment such as backboards, topdecks, KED's are on board each ambulance as well. As well ALS providers carry various medications such as Zofran, Albuterol, Nitroglycerin, Asprin, Morphine, Epinephrine etc. In addition, 700 has a RAD-57 CO detector, which is invaluable at a medical scene to rule out possible Carbon Monoxide poisoning.

This procedure is done through open heart surgery (sternotomy or thoracotomy) using an ECC where the heart is stopped to allow a system of special cannulas to be placed. The hole is closed by a direct suture (sewing) if the hole is small enough or if the hole is larger, suturing (sewing) a small patch of pericardium (heart tissue or skin) or fabric to close the hole. To increase quality life following ASD procedures/surgeries, patients should have a physical exam and ECG every 3, 6, and 12 months with their cardiologist. For many patients with secundum ASD closure repair, they can return to their normal activities unless their procedure was heart catheterization which in this case they should rest for a few days.

Nasal cannulas provide inspired oxygen fractions only slightly more than air, and are not of much benefit to injured divers. Air breaks are not necessary to avoid oxygen toxicity at surface pressure. ;Emergency oxygen supply: Sufficient oxygen to provide two divers with 100% oxygen at 15 litres per minute for long enough to reach further supplies of oxygen is standard equipment for commercial diving operations under the Scientific and Inshore codes of Practice in South Africa. ;Extrication and transportation equipment: An injured diver may need to be removed from the water in an inconvenient place, and special equipment such as a stretcher, spine board, high-angle rescue equipment or recovery slings may be required to get the casualty to a place more suitable for first aid, or to a vehicle for transportation to medical facilities.

Contour problems of the corrected gluteal region can be prevented with the operational use of small- gauge cannulas (ca. 2.0 mm) specifically for superficial liposuction; and with the application of cross-pattern harvesting of the excess body fat, to avoid removing too much adipose fat tissue, which might disfigure the contour of the patient's fat-donor area. The possible contour problems that might arise from ultrasonic liposuction are skin burns and hypertrophic scarring, which might occur if the fat-donor area skin is not cooled and protected during the fat harvest. To that end, the infusion of a tumescence-inducing solution to the fat-donor area(s) assists in cooling the patient's skin during the ultrasonic lipo-harvesting; likewise, the application of moist towels, a skin protector, and the constant cooling-fluid infiltration of the cannula in an integrated sheath.

Fat-graft breast augmentation: the pre-operative aspects (left) and the post-operative aspects (right) of a large-volume non- surgical augmentation In the study Fat Grafting to the Breast Revisited: Safety and Efficacy (2007), the investigators reported that the autologous fat was harvested by liposuction, using a 10-ml syringe attached to a two-hole Coleman harvesting cannula; after centrifugation, the refined breast filler fat was transferred to 3-ml syringes. Blunt infiltration cannulas were used to emplace the fat through 2-mm incisions; the blunt cannula injection method allowed greater dispersion of small aliquots (equal measures) of fat, and reduced the possibility of intravascular fat injection; no sharp needles are used for fat-graft injection to the breasts. The 2-mm incisions were positioned to allow the infiltration (emplacement) of fat grafts from at least two directions; a 0.2 ml fat volume was emplaced with each withdrawal of the cannula. The breasts were contoured by layering the fat grafts into different levels within the breast, until achieving the desired breast form.
