At what rate should chest compressions be performed during CPR for an adult?

The correct rate for performing chest compressions during CPR for an adult is between 100 and 120 compressions per minute. This recommended range is based on extensive research and guidelines established by organizations such as the American Heart Association and the American Red Cross.

The reason this rate is vital is that compressions at a pace of 100 to 120 per minute ensure that blood circulation is effectively maintained, which is crucial for the survival of a person experiencing cardiac arrest. At this rate, the compressions allow for adequate blood flow to vital organs, primarily the brain and heart, increasing the chances of successful resuscitation and positive outcomes.

A rate lower than 100 compressions per minute may not provide sufficient circulation, while a rate above 120 compressions per minute can lead to inadequate relaxation of the chest between compressions, which is also essential for blood return to the heart. Thus, performing compressions within the 100 to 120 compressions per minute range strikes a balance that optimizes the efficacy of CPR.
