Modern pocket masks have either a built in one-way valve or an attachable, disposable filter to protect the emergency responder from the patient's potentially infectious bodily substances, such as vomit or blood. [1] Many masks also have a built-in oxygen intake tube, allowing for administration of 50-60% oxygen.
Simple orinasal face mask for oxygen therapy at normal atmospheric pressure CPR pocket mask Bag valve mask. Part 1 is the flexible mask to seal over the patients face, part 2 has a filter and valve to prevent backflow into the bag itself (prevents patient deprivation and bag contamination) and part 3 is the soft bag element which is squeezed to expel air to the patient
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 ...
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 ...
An orinasal mask, oro-nasal mask, or oral-nasal mask [55] is a breathing mask that covers the mouth and the nose only. It may be a complete independent item, as an oxygen mask , or on some anaesthetic apparatus, or it may be fitted as a component inside a fullface mask on underwater breathing apparatus , a gas mask or an industrial respirator ...
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.
Demonstration of pocket mask use. Pocket Masks are used to provide rescue breaths similar to a bag valve mask, but the rescuer is using their own breath instead of a bag. The device consists of a mask attached to a one-way filter valve. The filter valve prevents bodily fluids such as blood vomit from entering the rescuer's mouth.
