    en.wikipedia.org/wiki/High_altitude_breathing...

    Both types of mask masks use a reservoir bag which can economise on oxygen consumption when the flow rate is set correctly for the current breathing rate by ensuring that the reservoir bag fully deflates at the end of inhalation and fully inflates by the end of exhalation. Some field user maintenance is possible using the spare parts kit.

  4. Oxygen therapy - Wikipedia

    en.wikipedia.org/wiki/Oxygen_therapy

    For patients requiring high concentrations of oxygen, a number of devices are available. The most commonly utilized device is the non-rebreather mask (or reservoir mask). Non-rebreather masks draw oxygen from attached reservoir bags with one-way valves that direct exhaled air out of the mask.

  5. Resuscitator - Wikipedia

    en.wikipedia.org/wiki/Resuscitator

    A resuscitator is a device using positive pressure to inflate the lungs of an unconscious person who is not breathing, in order to keep them oxygenated and alive. [citation needed] There are three basic types: a manual version (also known as a bag valve mask) consisting of a mask and a large hand-squeezed plastic bulb using ambient air, or with supplemental oxygen from a high-pressure tank.

  7. Oxygen mask - Wikipedia

    en.wikipedia.org/wiki/Oxygen_mask

    An oxygen mask is a mask that provides a method to transfer breathing oxygen gas from a storage tank to the lungs. Oxygen masks may cover only the nose and mouth (oral nasal mask) or the entire face (full-face mask). They may be made of plastic, silicone, or rubber. In certain circumstances, oxygen may be delivered via a nasal cannula instead ...

  8. Bag valve mask - Wikipedia

    en.wikipedia.org/wiki/Bag_valve_mask

    A bag valve mask can be used without being attached to an oxygen tank to provide "room air" (21% oxygen) to the patient. However, manual resuscitator devices also can be connected to a separate bag reservoir, which can be filled with pure oxygen from a compressed oxygen source, thus increasing the amount of oxygen delivered to the patient to ...

  9. Breathing apparatus - Wikipedia

    en.wikipedia.org/wiki/Breathing_apparatus

    A system which accumulates free-flow oxygen during resting and exhalation stages, (reservoir cannulas, partial rebreather masks and non-rebreather masks) makes a larger part of the oxygen available for inhalation, and it will be selectively inhaled during the initial part of inhalation, which reaches furthest into the lungs, and may also ...
