When a person performs cardiopulmonary (heart and lung) resuscitation (CPR), it is sometimes recommended to provide rescue breathing. This is certainly the case when the primary cause of the victim’s difficulty relates to failure to breathe adequately, such as with a drowning episode. When CPR first arrived on the landscape, laypersons were trained to perform mouth-to-mouth breathing (for adults) or mouth-to-mouth and nose breathing (for infants and small children).
Following growing concern about transmission of diseases from blood and body fluids, laypersons were introduced to using masks or something similar to allow them to provide breathing assistance (“artificial respiration,” “artificial ventilation,” “rescue breathing,” etc.) to non-breathing persons. Masks have been used for decades by professional rescuers for ventilating patients, often in conjunction with the use of bags in a “bag-valve-mask” configuration. The valve between the mask and bag provides for one-way flow and prevents the backwash of vomitus, blood, liquid from the lungs, or other fluids that might diminish the effectiveness of the technique.
A number of excellent masks and face shields are available on the market for rescuers to be able to (relatively) safely blow air into a victim’s lungs. One example is Read more »
