For more than an hour and a half, Snitzer had no pulse. Emergency room doctors said there was nothing more they could do. But one of the flight nurses who had come with the emergency helicopter had been trained in capnography. Snitzer's carbon dioxide levels suggested that blood was flowing to vital organs like the heart and brain, and the nurse thought Snitzer still had a chance.
The nurse "called the emergency room doctor, who told him that I was dead and that they should walk away," says Snitzer. "And he hung up and he said to the rest of the people in the room, 'Is anyone else here uncomfortable with walking away from this?' And they all said yes. And it was at that point that he called Dr. White."
Wow. Way to bring capnography (like sexy) back.
