Support Ordinary mountain sickness, a common condition among mountain climbers, and one from which most people can recover, is caused by the characteristic shortage of oxygen in the atmosphere at high altitudes. ████████ ██████ █ █████ ██████████ ██ █████ ███████████ ██ ███ █████ ████ ███████ ███████ ████████████████ ██ ███ █████████ ███████ ████ ███ ██████ ███ ████ ██ ██████ ██ █ ████████ ██ ███████ █████ ███ ████████ ██ ████████ █████ ████████ █████ ██ ████████ ████████ █████████ ████████ █████ ██ ██████████ █████████ ██ ████ ██████████
Summary
The author argues that cerebral edema (CE) is especially dangerous at high altitudes because it has similar symptoms to ordinary mountain sickness (OMS). The implication is that CE might be mistaken for OMS, so CE sufferers may not realize that they have a life-threatening condition.
Notable Assumptions
The author gives reason to believe that, at a high altitude, CE could potentially be mistaken for OMS, but doesn’t establish that this would be especially dangerous. For this mistaken diagnosis to increase the danger level, there would have to be some problematic course of action that would follow the misdiagnosis. If the same action would be taken to treat either condition, then CE wouldn’t be any more dangerous at high altitudes.
The argument depends on the assumption that a different course of action would be taken to deal with OMS than would be taken to deal with CE.
