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 ...
Oxygen piping and regulator with flow meter, for oxygen therapy, mounted in an ambulance Oxygen is widely used by hospitals, EMS , and first-aid providers in a variety of conditions and settings. A few indications frequently requiring high-flow oxygen include resuscitation , major trauma , anaphylaxis , major bleeding , shock , active ...
Lowering the oxygen content of a breathing gas mixture increases the maximum operating depth and duration of the dive before which oxygen toxicity becomes a limiting factor. Most trimix divers limit their working oxygen partial pressure [PO 2 ] to 1.4 bar and may reduce the P O 2 further to 1.3 bar or 1.2 bar depending on the depth, the ...
These are systems used to supply breathing gas on demand in a chamber which is at a pressure greater than the ambient pressure outside the chamber. [1] The pressure difference between chamber and external ambient pressure makes it possible to exhaust the exhaled gas to the external environment, but the flow must be controlled so that only exhaled gas is vented through the system, and it does ...

A store of oxygen, usually as compressed gas in a high pressure cylinder, but sometimes as liquid oxygen, that feeds gaseous oxygen into the ambient pressure breathing volume, either continuously, or when the user operates the oxygen addition valve, or via a demand valve in an oxygen rebreather, when the volume of gas in the breathing circuit ...
