When performing chest compressions, proper hand placement is very important. To locate the correct hand position place two fingers at the sternum (the spot where the lower ribs meet) then put the heel of your other hand next to your fingers (Figure 1).

Place one hand on top of the other and interlace the fingers (Figure 2). Lock your elbows and using your body's weight, compress the victim's chest. The depth of compressions should be at least 2 inches - remember: 2 hands, 2 inches (Figure 3).

Count aloud as you compress 30 times at the rate of about 3 compressions for every 2 seconds or approximately 100 compressions per minute.

Chest compressions will supply blood flow to the heart and the brain but if victim remains unresponsive you will need to check their airway
