Allow Time for Acclimatization

Persons coming into the mountains from low altitudes should be beware of trying to climb high peaks until they have had a few days to acclimatize. Many people who go too high too fast suffer "mountain sickness". The symptoms are vomiting, diarrhea, and the feeling of being very ill. Pulmonary edema, a major medical emergency, also can occur above the 9,000 foot level. The symptoms include extreme fatigue or collapse, shortness of breath, a racking cough, bubbling noises in the chest, and bloody sputum. Unless transported to a much lower altitude immediately, the victim may die within a matter of hours. If available, administer oxygen. The following chart lists the approximate length of time one should spend at various altitudes in order to become acclimatized:
Day 1.................0 ft - 7,000 ft.
Day 2.......7,000 ft.-10,000 ft.
Day 3......... 10,000 ft. - 12,000 ft.
Day 4..........12,000 ft. - 14,000 ft.

There are several other procedures which, if followed, may also help prevent the "mountain miseries".

Arrive in good physical condition.
Get plenty of rest and sleep.
Avoid alcohol and smoking.

Returning to sea level at the end of a high mountain expedition presents no adjustment problems.
