What is the recommended chest compression rate during adult CPR?

• A. 60-80 per minute
• B. 80-100 per minute
• C. 100-120 per minute
• D. 120-140 per minute

Answer: (C)

During adult CPR, aim for a chest compression rate of 100–120 compressions per minute. This range is chosen to balance delivering enough cardiac output to perfuse the brain and heart with the need to allow full chest recoil and proper compression depth. If the rate is too slow, perfusion drops and chances of return of spontaneous circulation diminish. If the rate is too fast, you risk shallower compressions and incomplete chest recoil, which reduces filling between compressions and the effectiveness of each compression. Using a metronome or a CPR feedback device helps maintain this rhythm within the recommended window.
