Abstract

This study compared and analyzed the change of air consumption according to water depth with human characteristics and theoretical values. The experimental results are as follows. First, subjects A and B showed similar rise rates depending on the water depth. Second, subject C had a significantly higher rate of increase in air consumption at 25m underwater because the body responded sensitively to deep water pressure, which increased air consumption because breathing was faster than other participants. Third, the subjects D and E showed significantly lower overall air consumption. D and E were 37 and 35 years of age, respectively, the youngest, strongest and most experienced in deep sea diving at the time of military service. Fourth, the average air consumption per minute of the test subjects increased from 5m in water to 1.45 times, 10m in water to 1.85 times, and 20m in water to 2.8 times. This seems to be a result of different experiences, physical fitness, the degree of adaptation of the body to underwater, and different breathing techniques. Lastly, the difference between the experimental average value and the theoretical value appears to be the result of using more or less air than the theoretical value depending on the experiences and physical strength of each of the 5 rescuers, the degree of adaptation of the body underwater, and the method of underwater breathing.

이 연구는 수심에 따른 공기소모량의 변화를 인간의 특성 및 이론값과의 비교·분석하였다. 실험 결과는 다음과 같다. 첫째, 실험대상자 A·B는 수심에 따라 각각 비슷한 상승률을 보였다. 둘째, 실험대상자 C는 수중 25m에서 공기소모량의 상승률이 유의하게 높게 나타났는데, 그 이유는 깊은 수심의 수압에 신체가 민감하게 반응하여, 호흡이 다른 참여자보다 다소 빨라 공기소모량을 증가시킨 것으로 보인다. 셋째, 실험대상자 D·E는 공기소모량이 전반적으로 유의하게 낮게 나타났다. 이는 D와 E의 연령이 각각 37세, 35세로 실험대상자 중 가장 젊고, 체력이 강건하며, 군 복무 당시 해상의 심해 잠수경험이 풍부하여 나타난 결과로 보인다. 넷째, 실험대상자 분당 평균 공기소모량은 수면과 비교하여 수중 5m는 약 1.45배, 수중 10m는 약 1.85배, 수중 20m는 약 2.8배로 분당 공기소모량이 증가하였다. 이는 구조대원 각자의 경험과 체력, 신체가 수중에서 적응하는 정도의 차이, 그리고 수중 호흡법이 달라서 나타난 결과로 보인다. 마지막으로 실험 평균값과 이론값의 차이는 실험대상자 구조대원 5명 각자의 경험과 체력, 신체가 수중에서 적응하는 정도의 차이 및 수중 호흡법에 따라 이론값보다 많거나 적게 공기를 소모하여서 나타난 결과로 보인다.
