What is the proper rate of chest compressions per minute for adults?

The proper rate of chest compressions for adults during cardiopulmonary resuscitation (CPR) is 100 to 120 compressions per minute. This range has been established based on research that indicates it provides the most effective blood flow to the heart and brain during a cardiac arrest. Compressions at this rate help to maintain adequate perfusion and increases the chances of survival for the victim.

This range is not too slow, which would be insufficient to keep the blood circulating, nor too fast, which could lead to less effective compressions and inadequate blood flow. The 100 to 120 compressions per minute rate reflects an optimal balance that aligns with the physiological requirements of the body during a life-threatening situation.
