Which of the following compression rates is considered appropriate during adult CPR?

During adult CPR, the recommended compression rate is 100-120 compressions per minute. This rate is established to ensure effective blood circulation and oxygenation to vital organs during cardiac arrest. Research and guidelines, including those from the American Heart Association, emphasize that compressions at this rate can optimize the chances of survival and improve outcomes for individuals experiencing cardiac arrest.

The rationale behind this specific range is based on the need to maintain adequate blood flow. Compressions that are too slow may not generate sufficient perfusion pressure to support circulation, while compressions that are too fast can be ineffective and may not allow adequate filling of the heart chambers between compressions. Therefore, aiming for a consistent rate of 100-120 compressions per minute provides a balance that maximizes cardiac output while minimizing the risk of fatigue for the rescuer during prolonged resuscitation efforts.
