TUCSON, AZ (Tucson News Now) - Northwest Fire District is offering free classes to teach the public the new standard in how CPR is performed.
Hands-only CPR does not require mouth-to-mouth breaths.
According to the University of Arizona's Sarver Heart Center, nearly 1,000 people die in the U.S. each day from sudden cardiac arrest.
"You don't know when you'll be put in a position to save someone's life," said Amy Allen.
More than two months ago, Allen called 911 after finding her 45-year-old brother Steven Smith face down inside the men's bathroom at Gladden Farms Community Park.
He had suffered an unexpected heart attack.
"Had my sister not done CPR, I wouldn't have survived at all," Steven said. "I definitely would not be here if Amy had not done what she had done. She had to do CPR for like seven minutes. She stuck with it until the EMTs arrived."
Northwest Fire officials said if you don't know CPR, now is the time to learn.
