What chest compression rate is recommended for adult CPR?

What chest compression rate is recommended for adult CPR?

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

Answer: (C)

Maintaining an appropriate chest compression rate during adult CPR is essential to maximize blood flow to the heart and brain. The recommended rate is about one hundred to one hundred twenty compressions per minute. At this pace, each compression generates forward blood flow while still allowing the chest to recoil fully between compressions, which is crucial for filling the heart again. If the rate is slower, there are fewer compressions each minute, reducing perfusion to the brain and heart. If the rate is faster, chest recoil can be incomplete and venous return may drop, also reducing effective blood flow. So, staying in the 100–120 per minute range provides the best balance for effective perfusion during CPR.
