There is no need to hurry or exert your self while acclimatizing. You shouldn�t climb higher than 300-500 meters/900-1500 ft per day. That�s not very hard to do and you might be tempted to go farther. But all it will bring you is headache,
sleeplessness and possibly mountain illness in the morning. Use your head, not your legs only.
These are the signs to watch for when climbing:
Some headache (relieved by aspirin), irregular breathing at night, rapid breathing at day, increased urine output.
Moderate mountain sickness
Some sleeplessness, decreased urine output, persistent headache not relieved by aspirin. Stay at your current altitude for some time (1-2 days) until you feel well. Don�t climb higher!
Acute mountain sickness (AMS)
Dizziness, vomiting, losing your balance, persistent coughing, sleepiness. Go down at least 500-m/1500 ft! Immediately.
Consult a doctor (on the walkie-talkie) and take emergency medicine.
High Altitude Cerebral (HACE)- and Pulmonary (HAPE) Edema
This is serious. Cerebral and Pulmonary Edema are caused by fluid collecting inside the brain and/or lungs.
Cerebral edema shows as failure of motor function, vomiting, hallucinations, extreme sleepiness and ataxia (can�t walk heel to toe). Try to walk a straight line or point your nose if you suspect it.
Oxygen, Gamow bag-treatment, Diamox and Decadron are helpful, but the most important is rapid descent.
The same treatment
counts for Pulmonary edema (blue lips, very heavy breathing, gurgling sound when breathing).
Both HACE and HAPE arrive upon pushing in spite of AMS. They are the immediate result of too much, too fast and a general negligence to the body's subtle or in the end, not so subtle
Sometimes we have to push the limits. Storms and other acute situations might force us into circumstances that we don�t like. That�s one thing. But to come up with AMS due to impatience and ignorance is sad. It could cost you your life.
HAPE and HACE kill fast.
Lastly, never cook inside a sealed tent. The gas withdraws the oxygen from the air and this can cause HACE/HAPE conditions in your sleep.
