Doctors find lowest blood-oxygen levels ever recorded in Everest climbersWe already learned that high-altitude mountaineering can seriously hurt your brain, so if you're still regularly bagging ultra high peaks, this next bit of bad news is unlikely to change your mind: Doctors have recorded the lowest blood-oxygen levels ever in climbers on Mt. Everest.
"By observing healthy individuals at high altitude where oxygen is scarce, we can learn about physiological changes that can improve critical care at the hospital bedside, because low oxygen levels are an almost universal problem in critical care," UCL doctor and expedition leader Mike Grocott said.
"These extraordinary low levels of oxygen found in high-altitude climbers may cause doctors looking after critically ill patients to revaluate treatment goals in some patients who have been ill for some time and might have adapted to low levels of oxygen in the blood."
Many climbers describe Everest as an overrated tourist peak, but these four climbers disproved the rule. Anyone who exposes their crotch at high altitude in the service of science and saving lives earns a hardman award in our book.
