What is the correct way to perform chest compressions?

The correct way to perform chest compressions involves using your body weight to push hard and fast at a rate of 100-120 compressions per minute, which is essential during cardiopulmonary resuscitation (CPR). This technique ensures that sufficient blood is pumped to the brain and vital organs when a person's heart has stopped beating effectively or at all.

Using body weight allows for deeper compressions, which is necessary according to guidelines from organizations such as the American Heart Association. The depth and rate of compressions are critical components that contribute to the effectiveness of CPR. Compressing at the recommended rate of 100-120 compressions per minute provides good blood flow during the cardiac arrest situation, maximizing the chances of a successful resuscitation.

While the other options present alternative methods, they do not align with the established guidelines for effective CPR. For instance, using only your fingertips does not provide adequate depth, and compressing lightly and slowly fails to create the necessary pressure needed to circulate blood effectively. Additionally, a rhythm of 70-90 compressions per minute is too slow to be effective, as it does not meet the recommended target for optimal outcomes during CPR.
