ROCHESTER, Minn. — Just the idea of performing CPR can intimidate the average person, whether it's the thought of what's at stake or simply trying to remember all of the steps. A move to simplify cardiopulmonary resuscitation practices for the public is one of many advances important to highlight during CPR Awareness Month, says Mayo Clinic resuscitation expert Roger White, M.D.

Now, rather than taking time to check airways or trying to recall how many breaths to give, the guidance for what a bystander untrained in CPR should do if someone collapses boils down to this: If the person doesn't respond to your command to awake, dial 911 to summon help, then immediately start continuous chest compressions. Press on the center of the chest as hard and as fast as you can — pushing about 2 inches down — and do it without stopping until help arrives to relieve you, says Dr. White, a Mayo Clinic anesthesiologist and a member of the American Heart Association scientific advisory committee that released the hands-only CPR call to action.
If someone else is there to assist, one person should call 911 and the other should immediately start chest compressions, Dr. White says. If you're not alone and there is an automated external defibrillator, start compressions and have someone else get and attach the AED. Continue compressions until the defibrillator tells you to stop.
Don't hold back on the force of chest compressions out of fear you will push too hard, he adds.
"It's very unlikely you are going to injure the chest, and remember, this patient is basically dead and you must do what you can," Dr. White says. "And that means to press on the chest as hard as you can and as fast as you can."
Let your weight do all that it can to produce the compression depth necessary, Dr. White says. Though it is tough, exhausting work, don't stop until someone can relieve you: The blood typically contains five to seven minutes worth of oxygen, and constant, fast chest compressions keep that oxygen moving to the brain and other vital organs, he says.
The move to make CPR more efficient and easier for the public to perform is one of several advances in resuscitation, Dr. White says. Among the others:
"All of this has opened up a whole new era for us," Dr. White says. "For me, this is the most exciting time to be in the world of resuscitation."
