(CNN) -- Debra Bader was taking a walk in the woods with her 53-year-old husband one morning when suddenly he collapsed. At first she thought the situation was hopeless. "I looked at him and said, 'He's dead,' because he wasn't moving or making any sounds at all," Bader remembers. "But I pulled the cell phone out of his pocket and called 911, and then a public service announcement I'd heard on the radio popped into my head."
