What is the recommended rate of chest compressions during CPR?

• A. 60 to 80 per minute.
• B. 140 to 160 per minute.
• C. 200 per minute.
• D. Approximately 100 to 120 compressions per minute.

Answer: (D)

Maintain a cadence of about 100 to 120 chest compressions per minute. This pace provides enough flow to perfuse the heart and brain while still allowing the chest to recoil fully after each compression. Going slower reduces blood flow between compressions, while going much faster can prevent complete chest recoil and lower the effectiveness of each compression. A practical way to stay in this range is to time compressions to a metronome or a song around 100–120 beats per minute, and couple that with the recommended depth and minimal pauses between compressions.
