How often should chest compressions be performed per minute?

  1. 50 times

  2. 75 times

  3. 100 times

  4. 125 times

The correct answer is: 100 times

Chest compressions should be performed at a rate of 100 times per minute during CPR. This rate is based on the American Heart Association's guidelines for performing CPR on adults, which recommends performing chest compressions at a rate of 100-120 compressions per minute. Options A, B, and D are incorrect as they do not follow this recommended rate and may not be effective in providing adequate circulation during CPR. It is important to perform chest compressions at the correct rate to ensure proper blood flow and increase the chances of survival in a cardiac emergency.
