What should be the rate of compressions during adult CPR?

The recommended rate of compressions during adult CPR is between 100 to 120 compressions per minute. This range has been established based on research and guidelines from organizations such as the American Heart Association. The rationale behind this recommendation is that a rate within this range optimally maintains blood flow to vital organs during cardiac arrest, increasing the chances of survival and decreasing the risk of brain injury.

Maintaining too slow a compression rate can lead to inadequate blood circulation, which is critical in the event of cardiac arrest. Conversely, compressing at a rate that exceeds 120 per minute may lead to decreased effectiveness, as proper depth and full chest recoil may not be achieved, compromising the quality of CPR.

Thus, the choice of 100 to 120 compressions per minute is aligned with the best practices in CPR training and is critical for maximizing the potential for a successful outcome.
