OKLAHOMA CITY -- John Faulkner left work at the Bone and Joint Hospital early.
The certified radiology nurse wanted to check the progress of his car at the downtown Firestone.
But the mechanic working on his car was nowhere to be found.
Faulkner said, "I called his name and I didn't hear anything."
John began exploring the garage and was mortified by what he found.
A pick up truck rolled off the ramps and on top of his experienced mechanic.
He said, "I could see he was blue. I tried to pull and he was stuck."
John called 911, raced for help and started CPR once employees freed the trapped victim.
Authorities say John's actions may have saved the mechanic's life.
Major Michael Paschel, with the Oklahoma City Fire Department, said, "Bystanders starting CPR, it's the number one factor in survival. So, when crews arrived they took over from there and were able to get a pulse."
EMSA medics transported the victim in critical, but stable condition.
Authorities said he's alive because a nurse happened to be in the right place at the right time.
