What compression rate should a trained rescuer use during adult CPR?
Correct answer: C. 100 to 120 compressions per minute
- A. 80 to 90 compressions per minute
- B. 90 to 100 compressions per minute
- C. 100 to 120 compressions per minute
- D. 120 to 140 compressions per minute
Explanation
Adult chest compressions should be delivered at 100 to 120 per minute to provide effective circulation. A slower rate may not maintain blood flow, while an excessively fast rate can reduce chest filling and compression quality.
