Observations were made as to the possible influence of simulated Apollo flight and lunar surface explorations on incidence of decompression sickness. Briefly stated, the various exposures of 19 men started with 3 hours of 'shirtsleeve' exposure to O2 at 'ground level.' Next, this was rapidly changed to either 60:40::O2:N2 or 80:20::O2:N2 at 5 psia. Four hours later the next decompression was to 3.5 psia O2 for 2 hours during which there were 4 bouts of 'rowing' for 4 min interspersed with 3 intervals of mark time. The measured rate of oxygen utilization during rowing ranged from 1.2 to 1.8 liter min/1 STPD depending on lean body mass. 'Bends' did not occur after decompression from 14.5 to 5 psia. There was a lesser incidence of bends after decompression to 3.5 psia O2 from 5 psia 80:20 than from 60:40::O2:N2. There was no correlation between the grade of bends and peak levels of energy expenditure resulting from rowing at 12 strokes per min against an identical tension. (Author)
