Doing Chest Compressions in an Adult
Doing Chest Compressions in an Adult

To do chest compressions for cardiopulmonary resuscitation (CPR), a rescuer kneels to one side and, with the arms held straight, leans over the person and places both hands, one on top of the other, just above (about two finger widths) the lowest part of the breastbone (called the xiphoid process). The rescuer compresses the chest to at least 2 inches (5 centimeters) in adults. The chest is compressed about 100 to 120 times per minute, allowing it to fully rise back up to its starting height, between each compression.
