最大自主通气量(MVV)可反映气道的动态功能,属肺功能检查的主要项目之一。但其要求受检者在一定时间内以最快速度、最大幅度完成呼吸运动,故有严重心肺疾病或咯血的患者则不宜作此项检查。第一秒用力呼气量(FEV_(1.0))也是反映气道
The maximum voluntary ventilation (MVV) can reflect the dynamic function of the airway, lung function test is one of the major projects. However, it requires the subject to complete the most rapid and maximum respiratory exercise within a certain period of time. Therefore, patients with severe cardiopulmonary diseases or hemoptysis are not advised to do so. The first second forced expiratory volume (FEV_ (1.0)) is also reflected airway
