When Not To Quit: Man Revived After 96 Minutes

Last January, a Minnesota man's heart stopped beating for an amazing 96 minutes. Emergency room doctors thought he was dead. But first responders who gave CPR on the scene decided not to give up, in part because of technology that allowed them to see their efforts were working. It's called capnography, and it measures how much carbon dioxide is being expelled with each breath. This information helps doctors and emergency medical personnel determine whether a patient is hyperventilating or having a heart attack. It also helps them decide how to treat an asthma attack, or determine whether CPR is working. viaNPR.org » When Not To Quit: Man Revived After 96 Minutes.
