  2. Spontaneous breathing trial - Wikipedia

    en.wikipedia.org/wiki/Spontaneous_breathing_trial

    A spontaneous breathing trial is a test for patients on mechanical ventilation, before they can be weaned from the ventilator, i.e. return to normal breathing.The weaning process depends closely on the patient's pathology, but the final common pathway to ventilator independence always includes at least one trial of spontaneous breathing.

  3. Heliox - Wikipedia

    en.wikipedia.org/wiki/Heliox

    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.

  4. Extracorporeal membrane oxygenation - Wikipedia

    en.wikipedia.org/wiki/Extracorporeal_membrane...

    Extracorporeal membrane oxygenation (ECMO), is a form of extracorporeal life support, providing prolonged cardiac and respiratory support to persons whose heart and lungs are unable to provide an adequate amount of oxygen, gas exchange or blood supply to sustain life.

  5. Trimix (breathing gas) - Wikipedia

    en.wikipedia.org/wiki/Trimix_(breathing_gas)

    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 ...

  6. Demand valve oxygen therapy - Wikipedia

    en.wikipedia.org/wiki/Demand_Valve_Oxygen_Therapy

    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 ...

  7. Air separation - Wikipedia

    en.wikipedia.org/wiki/Air_separation

    A nitrogen generator Bottle of 4Å molecular sieves. Pressure swing adsorption provides separation of oxygen or nitrogen from air without liquefaction. The process operates around ambient temperature; a zeolite (molecular sponge) is exposed to high pressure air, then the air is released and an adsorbed film of the desired gas is released.

  8. Autoxidation - Wikipedia

    en.wikipedia.org/wiki/Autoxidation

    The common mechanism is a free radical chain reaction, where the addition of oxygen gives rise to hydroperoxides and their associated peroxy radicals (ROO•). [5] Typically, an induction period is seen at the start where there is little activity; this is followed by a gradually accelerating take-up of oxygen, giving an autocatalytic reaction ...

  9. Oxygen tent - Wikipedia

    en.wikipedia.org/wiki/Oxygen_tent

    Oxygen therapy often benefits patients by providing more oxygen to their lungs and consequently to their tissues. Typically, the treatment raises the amount of oxygen in the blood, decreases load on the heart, and facilitates breathing. It can ease symptoms such as cough and dried up secretions that occur in respiratory conditions.
