What is the correct rate for chest compressions in CPR for adults?

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

Answer: (C)

The correct rate for chest compressions in CPR for adults is 100 to 120 compressions per minute. This range is crucial for effective cardiopulmonary resuscitation, as research has shown that maintaining this rate maximizes blood flow to vital organs during cardiac arrest. Compressions within this range help ensure that adequate pressure is applied to circulate oxygen-rich blood, which is essential for increasing the chances of survival.

In addition to the rate, it's also important to emphasize that the depth of compressions and allowing full chest recoil between compressions are key components of high-quality CPR. This combination of proper rate and technique contributes significantly to the effectiveness of the resuscitation effort.
