I watched Vertical Limit movie in which climbers of Himalaya mountain were contracted of pulmonary edema and needed a shot of something called 'dex' to help them survived. I want to know more about it, but only from the text book description. It'll be much better if any myLotters can share their experience in dealing with pulmonary edema. Who knows your story and sharing might help someone later =)
