避免肺量计检查中的误差。

Respir Ther. 1983 Mar-Apr;13(2):61-6.

Routine measurements of vital capacity, forced expired volume in one second, and forced expiratory flow are easy to make, and so are errors in these measurements. Even if the technologist observes all the rules in performing the tests, there is still a potential source of error in the machine.

肺活量、一秒用力呼气量和用力呼气流量的常规测量很容易进行，这些测量中的误差也是如此。即使技术人员在进行测试时遵守所有规则，机器中仍然存在潜在的误差来源。
