A pocket mask, or pocket face mask or CPR mask, is an expired air resuscitation device used to safely deliver rescue breaths during a cardiac arrest or respiratory arrest. It is a small portable device used in the pre-hospital setting to provide emergency ventilation to a patient who is either in respiratory failure or cardiac arrest.
The emergency responder is capable of delivering up to 16% oxygen with his/her breath. 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]
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 ...
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.
