  2. Respiratory failure - Wikipedia

    en.wikipedia.org/wiki/Respiratory_failure

    Respiratory failure results from inadequate gas exchange by the respiratory system, meaning that the arterial oxygen, carbon dioxide, or both cannot be kept at normal levels. A drop in the oxygen carried in the blood is known as hypoxemia; a rise in arterial carbon dioxide levels is called hypercapnia. Respiratory failure is classified as ...

  3. Respiratory arrest - Wikipedia

    en.wikipedia.org/wiki/Respiratory_arrest

    Respiratory arrest will ensue once the patient depletes their oxygen reserves and loses the effort to breathe. Respiratory arrest should be distinguished from respiratory failure. The former refers to the complete cessation of breathing, while respiratory failure is the

  4. Oxygen breathing apparatus - Wikipedia

    en.wikipedia.org/wiki/Oxygen_Breathing_Apparatus

    [1] The scrubber canister uses potassium superoxide as both a carbon dioxide absorbent and as an oxygen source. A sodium chlorate oxygen candle in the base of the unit generates oxygen on start-up as the canister has to reach a high internal temperature before it will start generating oxygen. The circulation of exhaled air containing carbon ...

    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.

  6. Oxygen tank - Wikipedia

    Oxygen tanks are used to store gas for: medical breathing (oxygen therapy) at medical facilities and at home (high pressure cylinder) breathing at altitude in aviation, either in a decompression emergency, or constantly (as in unpressurized aircraft), usually in high pressure cylinders; oxygen first aid sets, in small portable high pressure ...

  7. Breathing apparatus - Wikipedia

    en.wikipedia.org/wiki/Breathing_apparatus

    Closed and semi-closed circuit breathing sets, also known as rebreathers and gas extenders, are breathing apparatus that absorb the carbon dioxide from, and add oxygen to, a user's exhaled breath, allowing unused oxygen and diluent (if present) to be recycled. A rebreather system may be used for any application of a supplied gas breathing set.
