Dr. Kendra Fleagle Gorlitsky recalls the anguish she felt performing CPR on elderly, terminally ill patients.
It looks nothing like what we see on TV. In real life, ribs often break and few survive the ordeal.
"I felt like I was beating up people at the end of their life," she says. "I would be doing the CPR with tears coming down sometimes, and saying, 'I'm sorry, I'm sorry, goodbye.' Because I knew that it very likely not going to be successful. It just seemed a terrible way to end someone's life."
