1. CALL Check the victim forunresponsiveness. If there is no response, Call 911 and return to the victim. In most locations the emergency dispatcher can assist you with CPR instructions.
2. BLOW Tilt the head back and listen for breathing.  If not breathing normally, pinch nose and cover the mouth with yours and blow until you see the chest rise. Give 2 breaths.  Each breath should take 1 second.
3. PUMP If the victim is still not breathing normally, coughing or moving, begin chest compressions.  Push down on the chest 1½ to 2 inches 30 times right between the nipples.  Pump at the rate of 100/minute, faster than once per second.
CONTINUE WITH 2 BREATHS AND 30 PUMPS UNTIL HELP ARRIVES NOTE: This ratio is the same for one-person & two-person CPR.  In two-person CPR the person pumping the chest stops while the other gives mouth-to-mouth breathing.
