Compressions: Restore Blood Circulation
In order to determine if the victim’s heart is beating, place your index and middle fingers on the carotid artery, located in the depression between the windpipe and the neck muscles, and apply slight pressure for several seconds.
When performing chest compressions, proper hand placement is very important. Place the heel of one hand in the center of the chest (on the lower half of the sternum), then place your other hand on top and interlace your fingers.
Lock your elbows and use your body weight to compress the chest at least 2 inches deep. Push at a rate of 100–120 compressions per minute. Minimize interruptions and allow full chest recoil between compressions.
