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.
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 ...
Chemical oxygen generation is commonly used on large commercial aircraft as a source for the emergency oxygen system for passengers in pressurised cabins. The system is light and usually designed as a dispersed system to provide about 10 minutes supply of supplemental oxygen while the aircraft makes an emergency descent.
The amount of oxygen available to the patient in mouth-to-mouth is around 16%. If this is done through a pocket mask with an oxygen flow, this increases to 40% oxygen. If either a bag valve mask or a mechanical ventilator is used with an oxygen supply, this rises to 99% oxygen. The greater the oxygen concentration, the more efficient the ...
It is primarily used for treating severe cases of altitude sickness, [2] [3] high-altitude cerebral edema, and high-altitude pulmonary edema. [4] Like office-based hyperbaric medicine, the Gamow bag uses increased partial pressure of oxygen for therapy of hypobaric injury but has the advantage of portability for field use.
