摘要： 在不同的疲劳程度下，选取平地负重行进、低姿搜救、抬担架救人、受限空间行进、负重登楼5种典型战术动作，对测试者空气呼吸器的消耗速率以及心率进行监测。结果表明，耗气速率随着疲劳程度的升级而增高，最高是疲劳程度Ⅴ状态下进行负重登楼，为3.02 MPa/min，此时空气呼吸器的使用时间最短，为9.93 min。根据试验数据进行了火灾场景模拟，解决空气呼吸器实际使用时间和理论使用时间差异大的问题。

Abstract: The heart rate of participants and air consumption rate of breathing apparatus were monitored in real time under different fatigue levels and five typical tactical moves. The tactical moves were loaded traveling on a flat ground, low-posture searching, stretcher carrying, traveling in a confined space, and loaded stair climbing. As demonstrated by the results, the air consumption rate increased with increasing fatigue level and peaked at 3.02 MPa/min for loaded stair climbing under fatigue level Ⅴ; Meanwhile, the service life of the breathing apparatus was the shortest at approximately 9.93 min. A fire scenario simulation was conducted based on experimental data to solve the problem of significant differences between the actual and theoretical usage times of air respirators.
