When performing CPR, compressions should be which bpm?

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

Answer: (A)

During CPR, the speed of chest compressions must generate enough forward blood flow while still allowing the heart to fill and rebound between squeezes. The recommended rate is about 100 to 120 compressions per minute (roughly two per second). This range optimizes coronary and cerebral perfusion pressure and ensures complete chest recoil between compressions. Rates slower than this reduce perfusion, while rates faster than this can compromise depth and recoil, lowering cardiac output. So, the best rate is 100–120 compressions per minute.
