模拟153m深度快速上浮脱险潜艇艇员肺功能的改变

Changes in submariners' pulmonary function following the simulated 153 m fast buoyancy ascent escape

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 in submariners' pulmonary function following the simulated 153 m fast buoyancy ascent escape.Methods The Gould Spiroscreen cardiopulmonary instrument was used to measure various data of pulmonary function both before and after the fast buoyancy ascent escape in 7 submariners. Results When compared with control, the value of FEV 1.0,MMF and FEF50 % increased significantly at a 3 m escape depth, while FEV1.0 increased greatly at 80 m and 120 m escape depths ( P <0.05). All the other indices of pulmonary functions appeared normal (vs control, P >0.05). Conclusions The physiological and reversible changes in the submariners' pulmonary function in the experiment indicate that fast buoyancy ascent escape within allowable limit is a safe submarine escape method if submariners can manipulate it properly.
