The recommended chest compression rate is 100-120 per minute.

• A. 60-80 per minute
• B. 80-100 per minute
• C. 100-120 per minute
• D. 140-160 per minute

Answer: (C)

Maintaining a steady chest compression rate is crucial because it sets how much blood is delivered to vital organs over time. The range of 100–120 compressions per minute hits a balance: it’s fast enough to keep blood flowing to the heart and brain, but not so fast that you can’t press hard enough or allow the chest to recoil fully between compressions. If the rate is too slow, perfusion falls and organ blood flow suffers. If it’s too fast, compressions may become shallow and recoil might be incomplete, which also reduces effective blood return to the heart and overall perfusion. This is why this specific rate is recommended for effective CPR.
