What is the acceptable range for adult CPR compressions per minute?

The acceptable range for adult CPR compressions per minute is 100 to 120 compressions. This guideline aligns with recommendations from organizations such as the American Heart Association, which emphasizes the importance of maintaining a compression rate that is both effective in terms of circulation and sustainable during a resuscitation attempt.

At this rate, the compressions are strong enough to promote adequate blood flow to vital organs, particularly the brain and heart, which is critical in a cardiac arrest situation. A rate lower than 100 compressions per minute may not generate sufficient blood flow, while exceeding 120 compressions may lead to diminishing returns, increasing the likelihood of fatigue and potentially compromising the quality of each compression.

Monitoring the rate is crucial during CPR to ensure that the compressions remain effective throughout the resuscitation effort. Adjustments to the compression depth and rate are often necessary based on the rescuer’s fatigue and the patient's response, reinforcing the need for training and regular practice in these life-saving techniques.
