Nov. 30, 2005 -- The new rule of thumb for CPR is "push hard, push fast."
The new guidelines appear in Circulation.
The most significant change in the new guidelines is the higher number of recommended chest compressions, states an AHA news release.
The new guidelines call for a lone rescuer to provide 30 chest compressions for every two rescue breaths. That advice applies to victims of all ages, except for newborn infants.
The previous guidelines, issued in 2000, called for 15 chest compressions for every two rescue breaths. If two rescuers are performing CPR, then they are to follow the previous ratio of 15 chest compressions to two rescue breaths.
The change reflects research showing better survival by limiting interruptions in chest compressions, states the AHA.
The new guidelines also state that lay rescuers (people who aren't trained medical staff) don't have to check for signs of blood circulation before beginning chest compressions.
"The lay rescuer will be taught to begin chest compressions immediately after delivering two rescue breaths to the unresponsive victim who is not breathing," state the guidelines.
'Easy to Learn'
CPR is "easy to learn and do," says Robert Hickey, MD, in a news release. Hickey leads the AHA's emergency cardiovascular care programs.
Every year, an estimated quarter of a million unhospitalized people in the U.S. die of sudden cardiac arrest, write Mary Fran Hazinski, RN, MSN, and colleagues in an editorial in Circulation.
They add that "despite decades of efforts to promote CPR science and education, the survival rate for out-of-hospital cardiac arrest remains low worldwide, averaging 6% or less."
Ready, Willing, and Able
CPR can save lives, and Hickey says the AHA "believes the new guidelines will contribute to more people doing CPR effectively."
In a news release, the AHA calls for 911 dispatchers to be trained to provide CPR instruction by phone and to help callers correctly identify victims of cardiac arrest.
Besides providing the "push hard, push fast" advice, the guidelines also address issues for emergency medical staff, including the use of defibrillators.
"In the final analysis, the most important determinant of survival from sudden cardiac arrest is the presence of a rescuer who is trained, willing, able, and equipped to act in an emergency," write Hazinski and colleagues.
