초록

이 연구는 현장 소방활동에 따른 공기호흡기 소모량의 변화율을 파악 분석한 것으로 실험 결과는 다음과 같다. 대상자 5명의 평균 공기소모량은 가만히 서 있을 때 $15.56{\ell}/min$, 보통걸음으로 걸을 때 $32.43{\ell}/min$, 소방호스를 전개 하고 정리할 때 $43.07{\ell}/min$, 계단을 걸어 올라갈 때 $55.28{\ell}/min$, 계단을 뛰어 올라가 해머를 연속하여 내려치는 상황은 $127.14{\ell}/min$로 급격히 상승하여 에너지 소모량에 따라 공기소모량도 증가된다는 것을 알 수 있다. 실험대상자 A는 가장 고령임에도 가만히 서 있을 때 $13.23{\ell}/min$, 보통걸음으로 걸을 때 $29.33{\ell}/min$, 소방호스를 전개하고 정리할 때는 $41.08{\ell}/min$로 공기소모량이 가장 낮게 나타났다. 이는 깊고 느리게 하는 호흡법에 익숙한 결과로 판단된다. 실험대상자 D는 공기호흡기 평균 사용량이 $63.58{\ell}/min$로 유의하게 높았다. 그 이유는 비만이 공기소모량을 높인 것으로 보이고, 해머로 내려치는 동작에 체력이 소진되어 공기소모량 상승에 더 큰 영향을 미친것으로 판단된다. 실험대상자 E는 공기호흡기 사용량이 $49.90{\ell}/min$로 유의하게 낮게 나타났다. 그 이유는 E의 연령이 실험대상자 중 가장 젊고, 강인한 체력을 소유한 결과로 추측된다.

The purpose of this study was to identify and analyze the rate of change of air respirator consumption based on field fire fighting activities, The results of the experiment are as follows. The mean air consumption of the Five subjects was $15.56{\ell}/min$ when standing still, $32.43{\ell}/min$ when walking with normal pace, $43.07{\ell}/min$ when the fire hoses was expanded and arranged, $55.28{\ell}/min$ when climbing stairs, The situation of running up the stairs and hitting the hammer continuously increases to $127.14{\ell}/min$, which means that the consumption of air increases according to the energy consumption. Despite being the oldest, Experimental subject A was $13.23{\ell}/min$ when standing still, $29.33{\ell}/min$ when walking normally, and $41.08{\ell}/min$ when the fire hose was deployed and arranged. This is a result of familiarity with deep and slow breathing methods. The average respiratory use rate of subjects D was $63.58{\ell}/min$. The reason for this is that obesity seems to increase the air consumption, and it is considered that the physical strength is exhausted by the action of the hammer, which has a greater influence on the increase of air consumption. The subject E had significantly lower air respiratory use rate of $49.90{\ell}/min$. The reason for this is that the age of E is the youngest among the subjects, and it is presumed that it possesses strong physical strength.
