At what rate should chest cardiac compressions be performed in an adult?

The correct rate for chest compressions in an adult during cardiopulmonary resuscitation (CPR) is 100 to 120 compressions per minute. The option suggesting 80 times a minute comes the closest to meeting the recommended compression range but still falls short of the best practices outlined by organizations such as the American Heart Association.

In the context of CPR, effective chest compressions are crucial for maintaining blood circulation and oxygenation to vital organs. Performing compressions at the proper rate ensures that the heart can adequately pump blood and increases the chances of survival for the individual experiencing cardiac arrest. Compressing at too low a frequency, as indicated by the other rates provided—12, 24, and 50 times a minute—would not provide sufficient blood flow and could significantly reduce the effectiveness of the resuscitation efforts.

It is essential for anyone trained in CPR to remember and practice the guideline of 100 to 120 compressions per minute to maximize the chances of a successful outcome in emergency cardiac situations.
