The CPR breathing mask is used during cardiopulmonary resuscitation procedures, which are used in emergency situations to supply oxygen and produce blood flow in the heart and lungs.

The mask is used to ensure that infectious diseases, germs, blood, and other bodily fluids are not transferred from the resuscitator to the patient, or vice versa. There are many different types of masks on the market today which give rescue workers and those trained and certified to perform CPR a variety of safe and effective options when CPR has to be used.
