     Michelle Katz is a health-care saving expert with a master's degree in nursing,so when her husband

Martin had a heart attack right in front of her,she fought to save his life. Then,she fought the errors on his

medical bill and saved the

couple $ 7,000.

       Kaze was talking with her husband in June 2008 when she noticed his face tuming gray. "I looked

over and I said,Martin,are you OK?'"she told Good Morning America. "If I can describe death,that's

kind of what I was seeing.  And that's when I grabbed him.  And as I grabbed his hand,it was almost like

putting my hand in a vat (桶)  of ice cubes.It was that cold. He started stiffening up. "

      Terrified,Katz immediately gave her husband CPR.

       "I started pushing down on the compressions (压缩) and was just screaming and saying'Are you

OK? Are you still with me ? '"she said. "I just wanted him to know,even if he wasn't listening,that I was

not going to let someone die in my hands. And especially _____ "

        Later,X-rays showed that Katz had cracked her husband's ribs (肋骨)  with the force of her

compressions.  After 16 long minutes,an ambulance arrived and took Martin to the emergency room.

paying attention. She swore to follow the advice she had given others in Healthcare for Less and 101

Health Insurance Tips.

         "I knew the dollar signs were going up, " Katz said. "That's when I started documenting things. "In

the days that followed,Katz found errors on the bills that,when correctedlsaved her and her husband $

7,000.
