The Lung at High Altitude
When man ascends to high altitude or lives permanently at great heights, such as the High Andes of Peru and Bolivia, he becomes acclimatized to the conditions characteristic of the mountain environment. Virtually every system of the body is involved in this process. Since the major adverse environ-mental factor inherent in life at high altitude is hypoxia due to the diminished barometric pressure, one would expect that modifications in pulmonary structure and function would be prominent in acclimatization. Such is the case but we are still ignorant about many aspects of the condition of the lung at altitude that might be thought to be common knowledge.
