We confirm the finding of Behnke, et al.(1935) that air at 8· 6 atm. pressure has a somewhat
intoxicating effect on human beings, and that this effect is due to nitrogen. The nitrogen effect …

1. The time in which an animal or man exposed to compressed air becomes saturated with
nitrogen varies in different parts of the body from a few minutes to several hours. The …

The limits of 3% carbon dioxide and 17% oxygen in ambient air have beea accepted in the
American Submarine Service as compatible with efficient per-formance of personnel for …

DISCUSSION. Nature of the changes. The altered responses in air at high barometric
pressures can be produced also by a varietv of agents which depress the higher centers …

Group I. The subject sat in a chair and breathed commercial oxygen through a mask
connected with a Benedict apparatus. For pressures in excess of 1 atmosphere, the large …

The physiological reactions of two subjects were investigated in air at a temperature of 70–
100° F., and of 40–96 per cent. relative humidity. The experiments lasted 3 hours, and one of …

Paul Bert (1878) showed conclusively that high tensions of oxygen produce toxic effects. In
animals exposed to pressures above 3 to 4 atmospheres, the most striking characteristic …

in the partial pressure of CO2 and 02 in alveolar air at low pressures, in conjunction with the
symptoms produced. It was shown by Haldane and Priestley'that under normal con-ditions …

The respiratory effects of a 30-day exposure to an alveolar partial pressure of 171 ram. Hg
have been studied in 4 subjects at a total pressure of 700 ram. Hg (33.3 per cent 02) and 4 …

If P 1 is the pressure breathed by men for a prolonged period, and P 2 is the pressure to
which it is just safe to decompress rapidly, then assuming the volume of tissue gas released …
