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.
