Spring break and millions of kids are out of school--what could possibly go wrong?

Besides everything--and many of those who could help simply don't have the needed skills.

The Baylor Heart Hospital at Plano is trying to change that by getting kids to learn CPR.

16 year old Nicole Kennard signed up because she wants to babysit.

"I went in with the general knowledge you know, like knowing that I had to do compressions," Nicole said. "I needed to do mouth-to-mouth but not really knowing how to do those and what to do in that situation."

Nicole is not alone and that's why the American Heart Association simplified things by changing CPR guidelines to begin with chest compressions.

Nurse Michelle Sension said research indicates the survival rate is the same--so why not concentrate on the chest first until paramedics arrive to take over.

Michelle said the goal is to have more kids learn CPR because generally where there is one kid--there's a bunch of kids.

"Most of the time it's going to be students around them and giving them that knowledge of how to do basic CPR is the first step to saving a life," Michelle said.

In fact effective CPR delivered immediately after a heart attack can double the victim's chance of survival.

Dr. Warrett Kennard is a vascular surgeon--and Nicole's dad--he said the new CPR guidelines are a good idea.

"If somebody drops you've got four minutes to get circulation going," Dr. Kennard said. "If you can get some ventilation in there, wonderful, but the most important part of that is the compressions and getting blood to circulate."

Michelle said a good rule of thumb is time your chest compressions to the beat of the Bee Gees song "Stayin' Alive."

Nicole has no idea who the Bee Gees are--but she does know how to save a life.

"I feel like I won't panic as much because I had no idea what to do in that situation if I hadn't taken this course," Michelle said.
