Experts say effective bystander CPR doubles, or even triples a person's chance of survival if provided immediately after cardiac arrest.
David Schmidt can attest to those odds. He had a heart attack a few days before turning 45. His wife, Lyndi says her training just kicked in.
"I checked for his pulse, didn't feel a pulse and started doing CPR right away," Lyndi Schmidt said.
"Honestly, I've lost all memory of the incident and I've heard the stories," David Schmidt said. "It's almost like hearing about it happening to someone else, but I'm grateful to Lyndi and the San Francisco Fire Department."
