Chest Compression Placement During CPR for Adults

Cardiopulmonary resuscitation (CPR) is a critical life-saving technique that must be performed correctly to be effective. Every step in the CPR process is important and must be executed with precision. One of the most vital components of CPR for adults is delivering proper chest compressions.

Locating the Correct Compression Site

To perform chest compressions effectively, rescuers must locate the correct area on the chest. For adults, the recommended compression site is the lower half of the sternum, specifically at the midpoint of the line connecting the two nipples. This point lies at the junction of the upper and lower thirds of the breastbone.

Proper Hand Placement and Technique

The rescuer should kneel beside the victim and place the heel of one hand on the center of the chest at the identified location. The second hand should then be placed on top of the first, interlocking the fingers. The rescuer should keep their arms straight and position their shoulders directly above their hands.

Compression Depth and Rate

Effective compressions require the right depth and speed. Rescuers should press down firmly and smoothly to a depth of approximately 2 to 2.4 inches (5 to 6 centimeters). It's essential to allow the chest to fully recoil between compressions to enable proper blood flow.

In addition to proper technique, maintaining the correct rhythm is crucial. The recommended compression rate is between 100 and 120 compressions per minute. This steady pace helps maintain adequate circulation and increases the chances of a successful outcome.
