运用高压舱检查飞行人员耳气压功能

Examination of ear baric function of flying personnel in hyperbaric chamber

目的 :介绍高压舱检查飞行人员耳气压功能的方法及其安全性。方法 :根据低压舱法设计高压舱检查耳气压功能的压力变化速率、操作程序 ,确定检查耳鼓膜象的时机。结果 :用高压舱成功检查了 32名志愿者的耳气压功能。结论 :高压舱可用于检查耳气压功能 ,其安全性高于低压舱法。

Objective:To introduce a method and its safety in examining ear baric function of flying personnel in hyperbaric chamber. Methods: The hyperbaric chamber was designed according to the method of hypobaric chamber, and the change of velocity of ear baric function, the operating procedure and the time for examining eardrum membrane were examined. Results: The ear baric function of 32 volunteers was successfully examined in hyperbaric chamber. Conclusion:Hyperbaric chamber can be used to examine the flying personnel's ear baric function and its safety is higher than that of hypobaric chamber.
