DENVER -- A laid off paramedic who turned to delivering pizzas to make ends meet is credited with saving the life of a man who went into cardiac arrest just as a pizza was delivered to his door.

Christopher Wuebben, 22, was delivering a pizza late last week to the suburban Denver home of George Linn, when he heard the man’s wife screaming for help, according to Wuebben’s boss, John Keiley.

“Chris told the woman that he was trained in CPR and knew what to do,” Keiley, owner of Johnny’s New York Pizza, said on Tuesday. “He got him on the floor and brought him back to life before the fire department showed up.”

Linn was transported to Swedish Medical Center where he is listed in serious condition in the hospital’s critical care unit, hospital spokeswoman Julie Lonborg told Reuters.

Keiley said Wuebben is a military veteran who recently moved to Colorado after he was laid off from his paramedic job in Illinois. He said Wuebben is not scheduled to work at the pizza restaurant until later in the week, but Keiley may not have his new employee for long. At least one local hospital and a fire department have called to offer Wuebben a job in his chosen field after hearing of his heroics.

“He’s a good kid who was very nonchalant about what he did and hopefully this will work out for him,” Keiley said.
