2. 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 ...

3. Flow-restricted, oxygen-powered ventilation device - Wikipedia

   en.wikipedia.org/wiki/Flow-restricted,_oxygen...

   The main components of flow-restricted, oxygen-powered ventilation devices include An inspiratory pressure safety release valve. A trigger or level positioned to allow both hands to remain on the mask to provide an airtight seal while supporting and tilting the patients head. A peak flow rate of 100% oxygen at up to 40 L/min.

4. 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.

5. Respiratory arrest - Wikipedia

   en.wikipedia.org/wiki/Respiratory_arrest

   The bag-valve-mask device has a self-inflating bag with a soft mask that rests on the face. When the bag is connected to an oxygen supply, the patient will receive 60 to 100% of inspired oxygen. The purpose of bag-valve-mask is to provide adequate temporary ventilation and allow the body to achieve airway control by itself. However, if the bag ...

7. Mouth-to-mouth resuscitation - Wikipedia

   en.wikipedia.org/wiki/Mouth-to-mouth_resuscitation

   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 ...

8. High altitude breathing apparatus - Wikipedia

   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.

   Pulse oximeters came along in the 1980s as an easy and painless alternative. The device shines a light through the fingertip, seeking out oxygen-rich blood.
