他救型空气呼吸器供气时间研究

Research on extending gas supply time of the else-saving self-contained breathing appara

研究影响供气时间的因素,分析了不同运动状态、不同情绪、不同年龄段人群的呼吸量,得出了短时间内适当降低被救人员供气量是安全的结论。试验研究了剧烈运动后心率变化的规律,得到了至少需要4min心率才能恢复正常的结论。研究表明:采取适当降低被救人员供气量等措施可延长呼吸器供气时间1.4～10.0min。

The influence factors of gas supply time was studied, analysis was done on the breathing capacity of different emo tions, different sport conditions and different age groups. It is concluded that a lower gas supply to the rescued person for a short time is safe. Experimenal results show that it takes at least 4 minutes for the heart rate to return to normal after strenuous exercises. With a lower gas supply, the supply time can be prolonged by 1.4 to 10.0 minutes.
