AMS: Acute Mountain Sickness (minor)
HAPE: High Altitude Pulmonary Edema (severe): water in lungs
HACE: High Altitude Cerebral Edema (severe): water in brains
Causes of Altitude Sickness:Low barometric pressure
Less oxygen
Hypothermia
Fast climbing
DehydrationMinor Symptoms of Altitude Sickness:Hangover

Do not travel aloneUseful Tips:Have detailed knowledge regarding altitude sickness before being engaged in the trekking
In case of mild suffering, do not make the patient climb up and give aspirin
If the condition worsens, take the patient at lower altitude
Never leave the teamTreatment:Bring the patient to the lower altitude as soon as possible, do not wait for rescue team
Supply enough oxygen
In case of minor altitude sickness, give diamox 125mg before dinner
Give Nafedipine for patient of HAPE
