abstract="Measurements of ambient oxygen concentrations were made in 22 commercial flights (707 and DC-9 aircraft) starting at an altitude of 1,500 meters (5,000 feet) with two oxygen analyzers, one calibrated at sea level (158.8 torr) and a second for Denver's altitude. Peak &quot;pressurized cabin&quot; altitudes ranged between 6,050 and 8,450 feet when &quot;cruising altitudes&quot; varied between 29,000 and 37,000 feet. In the former analyzer, the lowest oxygen concentrations noted were about 15.2% (15.5 torr), while in the latter, they were 17.6% (133.7 torr). The possible dangers of temporary hypoxia to patients with cardiac, pulmonary, and hematologic diseases, while flying under these circumstances, are discussed.<p /><p>Language: en</p>",
