- Figure out what’s needed. Make sure that the environment is safe and secure, then tap the person on the shoulder and ask if they are ok. If they’re unconscious, check to see if they are breathing and have a pulse. If there is no breath or pulse call 911 yourself or ask another bystander to do it. This is the first, and most important thing to do in order to activate emergency personnel.
- Start helping the heart beat. As you begin CPR, check for an automated external defibrillator (AED). AEDs can electrically shock the heart and cause it to start again. Many locations have these devices mounted on walls for use in emergencies. Check for a pulse. If you cannot detect a pulse, prepare the patient for chest compressions. First make sure there have been no neck injuries. Lightly tilt the victim’s head back to lift their chin. Kneel and place the heel of your hand on the person’s chest between their nipples. If you are performing CPR on an adult, place the heel of your other hand on top and intertwine your fingers. Straighten your elbows and align your shoulders over your hands. Using your upper body weight, start your compressions. The goal is to perform 100 to 120 compressions each minute, allowing the chest to rise after each compression. To assist with timing, compress the chest down and release while counting “One-and-two-and-three…” Although it may sound strange, you can perform them to the beat of the Bee Gees song, “Stayin Alive” and this aligns with the appropriate timing.
- Only do rescue breaths if you’ve been trained. The American Heart Association recommends that only people who have been taught how to do rescue breaths attempt this part of CPR (everyone else should stick to the chest compressions). If you’ve been trained and the victim isn’t breathing, do two rescue breaths after every 30 compressions. With their head tilted back and chin lifted, pinch their nose shut and place your mouth over the victim’s mouth. Blow into their mouth (you should notice that their chest starts to rise when you do this). After two breaths, resume compressions if necessary.
