摘要: 建立了爆炸减压时肺泡氧分压随时间变化的房室数学模型,对于分子筛供氧情况下爆炸减压过程进行了数值模拟,模拟结果和实测结果能够很好的符合.分析了飞行高度及供氧浓度对过程的影响.此模型为求解爆炸减压时肺泡氧分压降到临界值的时间提供了一种简单的方法,对高空飞行医务监督和应急供氧装备的设计有实际意义.

Abstract: A simple mathematical model about the dynamic variation of alveolar oxygen partial pressure during explosive decompression is established in this paper. With this model the process of alveolar oxygen pressure change during explosive decompression process is simulated with molecular sieve oxygen generating system(MSOGS). The effects of concentration of supplying oxygen and the flight altitude is analyzed. The predicting and experimental results are in good agreement. This model provides an easy approach to calculate the critical time for the explosive decompression process. It is helpful for design of life-support equipment and medical watch of high altitude flight.
