High Altitude Cerebral Edema Warning
High altitude cerebral edema warning means confusion, ataxia, or severe headache at elevation—immediate descent and emergency care, never solo continuation.
High altitude cerebral edema warning covers confusion, staggering gait, severe headache, vomiting, and behavior changes after altitude exposure—HACE is a medical emergency. It can progress from untreated AMS within hours.
Never leave someone with ataxia alone; initiate descent and emergency help immediately.
Common questions
-
What is the first action if someone shows ataxia at altitude?
Stop ascent, buddy-monitor, begin descent, and activate emergency medical support. Do not wait for morning or try to sleep it off at the same elevation.
