A gloss of Chronic Hypoxia in normal and diseased individuals at high altitude

摘要：

@@ IntroductionMillenary populations that live at high altitude in different continents like Asia (1) and South America (8), have endured biological adaptation in very adverse environmental conditions, of which to our understanding, paradoxically, chronic hypoxia is the most tolerable. Patients with pulmonary diseases at high altitude tolerate tissue hypoxia with an arterial tension (PaO2) even as low as 30 mmHg. Current scientific knowledge has made progress in many areas, clarifying many doubts, however due to preconception and lack of broad social studies chronic hypoxia is still not fully understood. Beings that inhabit different areas of the planet earth have lived under a variety of different hostile conditions: intense cold in the polar regions,intense heat in Africa and in the Middle East desserts,great pressure in the depth of the oceans, intense darkness of the caves and naturally the hypoxia of extreme altitudes.
