为制订我国军用航空供氧装备附加呼吸阻力容许限值,在我室近年实验研究的基础上,选用我国军用飞机装备的YX-1与YX-3两种供氧系统进行装备附加呼吸阻力实验。其目的在于:利用开式“人工肺”测出两种系统的压力与流率(P—V)关系;在已知装备系统阻力的基础上,分别在静坐、轻和中度(250和600kgm·min~(-1))体力负荷下,测出面具腔压力波动幅度((?))与人体感觉量间的关系;将实测结果与我们已初步确定的附加呼吸阻力容许限值进行比较,对现用的两种供氧系统的呼
In order to set the allowable limit of the additional respiration resistance of China’s military aviation oxygen equipment, based on the experimental studies in recent years in our country, two types of oxygen supply systems, YX-1 and YX-3, equipped with military aircraft in our country, were selected for the additional respiratory resistance test. The purpose of this study was to determine the relationship between pressure and flow rate (P-V) of the two systems using an open “artificial lung”. On the basis of known resistance of the equipment system, · Min ~ (-1)), the relationship between the amplitude of the mask cavity pressure fluctuation ((?)) And the sensation of the human body is measured. The measured results are compared with the allowable limits of additional respiratory resistance that we have initially determined. Call now on two types of oxygen supply system
