New guidelines drop the ‘P’ from CPR

After 50 years of loyal service, traditional CPR is being replaced by a new, bare-bones version of the life-saving emergency procedure.
Forget about yucky mouth-to-mouth contact—the P in Cardiopulmonary resuscitation (CPR)—and get right down to pumping hard and fast on the chest, the American Heart Association said on Monday,
That will keep oxygen-rich blood flowing to the brain until trained rescuers can take over.
"Chest compressions are the most important part of CPR,” said Dr. Michael Sayre, a spokesman for the American Heart Association. “The major change is switching to starting CPR with chest compressions rather than opening an airway and doing rescue breathing.”
Only if a rescuer has been specifically trained in conventional CPR should they give rescue breathing as well, added Sayre, also of Ohio State University in Columbus.
Recent studies have shown that CPR without rescue breathing works as well as or better than the full version in most people who suffer cardiac arrest.
And it might also get more people to do CPR, which is currently performed only about half the time when someone witnesses a person collapse from cardiac arrest. Some 300,000 Americans suffer cardiac arrests every year, and less than one in 10 survive.
That dismal number hasn’t changed in three decades. But doctors say it could, and part of the solution is to get more bystanders to roll up their sleeves and start chest compressions in the center of the chest.
The ideal rate is at least 100 compressions per minute—coincidentally, about the same pace as the Bee Gees 1977 disco hit “Stayin’ Alive.” Each compression should be about two inches (five centimeters) deep in adults and children, and about one and a half inches in infants. Rescuers should not lean on the chest between compressions; it’s important to let the chest return to its starting position.
“If you see the victim suddenly collapse—one minute they’re walking and talking and the next minute they are on the ground—then the odds are high that it is cardiac arrest,” Sayre said.
If the victim is not breathing or not breathing normally, “Tap on their shoulder to see if you can wake them up. If you can’t, then we recommend starting chest compressions after calling 911.”
If you start CPR on someone who collapsed for some reason other than a cardiac arrest, “they usually just wake up,” said Sayre, adding that serious injuries were rare.
Earlier this month, Arizona saw the effects of a state-wide campaign to get bystanders to do hands-only CPR.
Five years after health officials started promoting the technique, the chances of surviving a cardiac arrest had more than doubled, reaching close to 10 percent. And those victims who received hands-only CPR had more than 1.5 times the odds of making it compared to those who got conventional CPR (see Reuters Health story of Oct 5, 2010).
“I don’t see any reason why in the future you wouldn’t have a better chance of surviving than dying of a cardiac arrest,” Dr. Bentley J. Bobrow, of Arizona’s Bureau of Emergency Medical Services & Trauma System, told Reuters Health at the time.
He noted, however, that factors such as public-access defibrillators—which can jolt the heart back to its normal rhythm—and better hospital care are also important.
For people who are trained in conventional CPR, the new guidelines recommend giving two breaths after 30 compressions, and then repeating the cycle.
That may be especially helpful for many children and people who have drowned, because their blood is out of oxygen.
But for the majority of American adults with cardiac arrest, the heart gives in suddenly because the arteries that supply it with blood get clogged by cholesterol. For those people, keeping the blood flowing without interruption appears to be vital.
The American Heart Association has created a short web tutorial that shows how to do effective CPR. It’s available at http://handsonlycpr.org/.

Once it was the A-B-Cs of CPR. Now the American Heart Association claims it???s time to change things up, accounts CBS News. Now, C-A-B is A-OK when it comes to cardiopulmonary resuscitation (CPR). The American Heart Association and American Red Cross feel that new CPR guidelines (Compression, Airway, then Breathing) and methods for administering first-aid represent a more consistent, life-saving process. Ultimately, learning the new order can be vital for any life-saving individual.
