How to do CPR on an Adult (Ages 12 and Older)

Continue cycles of 30 compressions and two breaths until you see signs of life, another rescuer takes over, or help arrives.

Check for breathing and signs of life by watching their chest for normal movement for no more than 10 seconds. If there's no breathing or signs of life, begin CPR.

To perform chest compressions, position the heel of one hand on the center of the adult's chest, place your other hand on top, lock your elbows, and keep your arms straight. Lean over the chest and compress it 2 inches deep, 30 times.

After 30 compressions, give two rescue breaths. Tilt the head back, lift the chin, and pinch the nose. Place your mouth over theirs and give two slow, gentle breaths, just enough to make their chest rise.

Upon arriving at the scene, ensure safety, then check the victim for consciousness by gently tapping their shoulder and shouting. If there's no response, immediately call 911. If the adult is on their stomach, turn them onto their back on a hard, flat surface.
