In CPR for an adult, what is the recommended rate of chest compressions per minute?

• A. 80 compressions per minute
• B. 90 compressions per minute
• C. 100 compressions per minute
• D. 120 compressions per minute

Answer: (C)

During adult CPR, a steady, fast pace for chest compressions is essential to keep blood flowing when the heart isn’t pumping. The guideline target is about 100 to 120 compressions per minute. This range provides enough force and speed to maintain perfusion without compromising chest recoil or causing excessive fatigue for the rescuers. In many training settings, 100 compressions per minute is used as the standard target because it sits safely in the middle of that recommended range and is easier to teach and track. Compressing too slowly (like 80 or 90 per minute) reduces blood flow to the heart and brain, while compressing at the upper end (around 120) is acceptable but can be harder to maintain with proper depth and recoil for many responders. Aim for about 100 compressions each minute, ensuring each compression is deep enough (about 2 inches or 5 cm for an average adult) and allowing full chest recoil between compressions, with minimal interruptions.
