Since a bar of pressure is reckoned to be normal for sea level, this image demonstrates that on Kilimanjaro's summit each breath comprises half the amount of oxygen we enjoy at sea level. In bad weather the pressure drops further still, so the amount of available oxygen is further reduced. Carl, battling against altitude-induced exhaustion en route to Barafu (4681m).
