Immediate descent is the treatment of choice
If descent not possible use combination of:
Supplemental O2 (goal SpO2 90%)
Supportive hyperventilation
Dexamethasone 8mg initially (PO, IM, or IV), then 4mg q6hr
Acetazolamide 250mg BID (better as ppx)
Hyperbaric bag (Gamow bag) if available
Of note, furosemide, mannitol, and oral glycerol have all been studied but have undetermined effectiveness at this time.
