“…Typically pilots do not recognize that the hypoxia caused the later fatigue. McFarland (1975) and Houston (personal communication) suggest that long passenger trips at normal airline cabin altitudes of 2000 meters cause perceptible fatigue.…”

“…Githens et al (1977) recommend blood screening: "The increased risk of splenic sequestration or infarction at high altitude for persons with S/C hemoglobin may present an additional reason for hemoglobin screening of appropriate groups in the mountain states or for those planning recreation or travel in the high mountains. Two of our patients were unaware of their hemoglobinopathy prior to the episode, and the other three had not been counseled regarding any risk associated with mountain travel/' III.4.7 Preexisting Circulatory or Respiratory Disorders It is expected that altitude will affect existing circulatory or respiratory disorders (McFarland 1975;Hultgren 1979), but no data have been published on such problems (Hultgren, personal communication). Any disorders that lead to unsaturation of the hemoglobin at sea level will be accentuated at altitude, but chronic pulmonary obstructions without unsaturation probably will not be affected.…”

“…Carbon monoxide is an especially serious pollutant, because it specifically reduces the oxygen carrying capacity of the blood. The average chronic smoker has between 4% and 8% of saturation of his hemoglobin with CO, increasing his physiological altitude by about 1000 meters (McFarland 1975). Nearby people will be affected, and it will be necessary to limit smoking.…”

The research literature on high-altitude physiology and medicine is reviewed. High-altitude effects on performance are often larger than recognized either by its victims or their colleagues at the same altitude. At 4000 meters most unacclimatized people will lose very roughly 20% of their sea level abilities, and some loss may persist after moderate acclimatization. At least half the people with no acclimatization will suffer some sickness starting a few hours after ascent and lasting a few days. Between 0.1% and 1% of the individuals going to 4000 meters altitude will suffer serious illness at some time, and that illness may become life threatening if the victim does not descend. The anecdotal reports of astronomers working at high altitude are discussed, and reasons for their variation are suggested. It is concluded that the problem is larger than sometimes recognized, and preliminary engineering costs are given for some solutions.
