| Abstract: | Prior to evaluating an underwater breathing apparatus (UBA), diver performance must be determined. Previous studies determining the oxygen consumption of swimming and resting divers were done in the laboratory and were limited in scope. Criticisms of those studies suggested that they may not have accurately simulated the underwater work expected of an operational diver. This study measured the oxygen consumption (VO2) sustained by experienced Special Warfare (SPECWAR) operators participating in training exercises. By using a closed-circuit oxygen underwater breathing apparatus, the decrease in the oxygen bottle pressure reflected the amount of oxygen consumed by the diver. Combat swimmers, swimming at their own pace, had a mean V.O2 of 1.5 +/- 0.2 (SD) liters per minute (lpm), (n=8). Resting divers mean V.O2 was 0.64 +/- 0.09 (SD) lpm (n=12). These values are comparable to the results of the previous studies. Guidelines reflecting underwater oxygen consumption and estimating carbon dioxide production for calculating carbon dioxide canister duration should be based on the results of these studies. |
