DANVILLE -- Football fans can learn a hands-only way to tackle sudden cardiac arrest at training sessions Friday during San Ramon Valley High School's junior varsity and varsity football games.

The training will be at halftime at both games. The CPR tent will be set up near the field. Participants will learn the CPR technique and proper use of an automated external defibrillator (AED).

"With the hands-only CPR method, learning CPR is a snap," said Capt. Andy Swartzell of the San Ramon Valley Fire Protection District. "If you see an adult collapse, simply call 9-1-1 and then push hard and fast in the center of the patient's chest until help arrives and takes over for you."

Nationally, a person with a sudden cardiac arrest outside of a hospital has an 8.5 percent of survival. That rate is as high as 17.9 percent in the San Ramon Valley, according to studies. The likelihood of survival jumps to 46.9 percent if an AED is used to jump-start the heart.

The junior varsity game starts at 4:30 p.m., varsity at 7 p.m.

the teams will play Livermore High. The stadium is at 501 Danville Blvd.

CPR training is hosted by the San Ramon Valley Fire Protection District and its HeartSafe program.
