目的 观察模拟大深度快速上浮脱险实验时潜艇艇员肺功能的改变。方法 采用 GouldSpiroscreen肺功能仪 ,测定 7名艇员试验前对照值和试验后肺通气功能各项指标。结果 7名艇员在3m深度 FEV1.0、MMF、FEF5 0 %三个指标均比对照值增高 (P<0 .0 5 ) ,80和 12 0 m深度 FEV 1.0均比对照值增高 (P<0 .0 5 ) ;其余各项肺功能指标在各深度与 0 m (常压 )比较 ,差异均无显著性。结论 大深度快速上浮脱险虽然对机体肺功能产生了一些影响 ,但都属生理性改变 ,提示在深度允许的情况下 ,只要按照正确的方法操作 ,快速上浮脱险技术是安全可靠的。
Objective To observe the changes of lung function of submarine crew during the experiment of simulating deep and rapid ascendance. Methods The GouldSpiroscreen pulmonary function test instrument was used to determine the control values of seven sailors before the test and the indexes of the pulmonary function after the test. Results The three indicators of FEV1.0, MMF and FEF50% at 7m depth were significantly higher than those at the 3m depth (P <0.05), and FEV 1.0 at 80 and 1200m depth was significantly higher than that of the control (P < 0 .0 5). There was no significant difference in the remaining indexes of pulmonary function at 0 m (atmospheric pressure) at all depths. Conclusions Although the deep and rapid exhumation has some effects on the lung function of the body, all of them are physiological changes, suggesting that the rapid ascent and de-escape technique is safe and reliable provided that the depth permits.
