Cardiopulmonary resuscitation, an approach to reviving a man whose breathing has ceased. CPR is a lifesaving treatment. Respiration may have quit due to blocked air passages, a jolt, high temperature, or various other reasons. CPR training can be found through various charitable organizations.

There are two main kinds of CPR. Fundamental CPR is important for everyone to understand. This contains the fundamentals about respiration and education on chest compressions to restart the heart once discontinued. The second kind is advanced cardiac life support (ACLS), which is a technique offered to health-care professionals and which needs additional training.
