Medical gas therapy is a treatment involving the administration of various gases. It has been used in medicine since the use of oxygen therapy. [1] Most of these gases are drugs, including oxygen. [2] Many other gases, collectively known as factitious airs, were explored for medicinal value in the late eighteenth century. In addition to oxygen ...
Heliox is a breathing gas mixture of helium (He) and oxygen (O 2).It is used as a medical treatment for patients with difficulty breathing because this mixture generates less resistance than atmospheric air when passing through the airways of the lungs, and thus requires less effort by a patient to breathe in and out of the lungs.
Demand Valve Oxygen Therapy (DVOT) is a way of delivering high flow oxygen therapy using a device that only delivers oxygen when the patient breathes in and shuts off when they breathe out. DVOT is commonly used to treat conditions such as cluster headache , which affects up to four in 1000 people (0.4%), [ 1 ] [ 2 ] [ 3 ] and is a recommended ...
Medical oxygen storage tanks at the Royal Women's Hospital, Melbourne, Australia. Oxygen may be used for patients requiring supplemental oxygen via mask. Usually accomplished by a large storage system of liquid oxygen at the hospital which is evaporated into a concentrated oxygen supply, pressures are usually around 345–380 kPa (50.0–55.1 psi), [1] [2] or in the UK and Europe, 4–5 bar ...
The International Pharmacopoeia specifies that Medical oxygen produced by air liquefaction has a purity of at least 99.5% oxygen by volume. The World Health Organization (WHO) specifies that for pressure swing adsorption (PSA) plants, medical oxygen produced from ambient air has 93±3% oxygen, and for oxygen concentrators, 82% from room air (21 ...
Oxygen is naturally occurring in room air at 21% and higher percentages are often essential in medical treatment. Oxygen in these higher percentages is classified as a drug with too much oxygen being potentially harmful to a patient's health, resulting in oxygen dependence over time, and in extreme circumstances patient blindness.
An oxygen concentrator takes in air and removes nitrogen from it, leaving an oxygen-enriched gas for use by people requiring medical oxygen due to low oxygen levels in their blood. [4] Oxygen concentrators provide an economical source of oxygen in industrial processes, where they are also known as oxygen gas generators or oxygen generation plants.
Nitrous oxide, as medical gas supply, is an inhaled gas used as pain medication, and is typically administered with 50% oxygen mix.It is often used together with other medications for anesthesia. [2]
