What is the correct rate of CPR compressions for adults?

The correct rate of CPR compressions for adults is 100-120 compressions per minute. This range is supported by guidelines from organizations such as the American Heart Association, which emphasizes that adequate compression rate is crucial for maintaining blood circulation during cardiac arrest.

Performing compressions at this rate helps to optimize the blood flow to vital organs, enhancing the chances of survival until professional medical help arrives. Compressions should also be deep (at least 2 inches) and allow for complete chest recoil between compressions to maximize blood return to the heart.

Maintaining a rhythm that aligns with the correct rate can be aided by using a metronome or performing the compressions to the beat of a song like "Stayin' Alive," which is approximately 104 beats per minute. Other options reflect incorrect ranges that would be either too slow to be effective or above the recommended rate, which could lead to fatigue and inefficient CPR delivery.
