COLLIER COUNTY, Fla.- A new study published in The Lancet suggests doctors give up too soon when it comes to performing CPR.

Dr. Ronald Levine is the president of the local American Heart Association chapter and also a cardiologist at the Naples Heart Institute. He says the results of the study seem counter-intuitive. It also goes against the theory that prolonged CPR could result in neurological damage.

The study says an additional nine minutes of CPR in a hospital setting could save more lives. The study looked at more than 400 hospitals over an 8 year period.

He says, "I think its an interesting finding, I think its not a definitive finding, I believe there is not a lot of cost to continue CPR for an extra few mintues."

He says what really matters is the cause of the cardiac arrest. He says the extra time could make a difference for some patients, but everyone is different.

Dr. Levine doesn't expect any changes in policy or guidelines, but does expect doctors will discuss the findings. He says it may make them think about prolonging CPR for patients who may benefit.

Phil Daniels is a CPR instructor, paramedic, and heart attack survivor. He knows how important the life-saving skill is, and encourages everyone to learn how to do it. "It's pretty much near and dear to my heart now. Literally. So the importance of what they're doing and to do it properly is of utmost concern to me."
