How many chest compressions per minute are recommended?

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

Answer: (A)

The key idea is the pace of chest compressions during CPR. The recommended rate is about 100 to 120 compressions per minute. This range balances delivering enough blood flow with the chest having time to recoil fully and for compressions to stay deep enough. If you go too slow, perfusion to the heart and brain drops; if you go too fast, you risk shallower compressions and fatigue that reduce effectiveness. A practical tip is to use a metronome or a tempo around 100–120 BPM to help maintain the rhythm. The other rates are outside this effective balance: slower rates decrease perfusion, while faster rates can compromise depth and recoil.
