time vital capacity

Method The tidal volume, vital capacity, time vital capacity and minute ventilation volume were observed in 600 students.

方法用肺量计测定6 0 0名大学生的潮气量、肺活量、时间肺活量及每分钟通气量。

An investigation is made on 1653 college students aged 18 to 24 in good health about their Vital Capacity (VC) and the Breath-Holding Time (BHT).

对年龄在18 ~ 24岁间的1653名健康大学生的肺活量和屏气时间进行了调查。

Conclusion Maximum phonation time, the mean airflow rate and ratio of phonation volume to vital capacity can be used as indicator in clinical application.

结论最长发声时间可作为衡量嗓音功能的有效指标之一。发声气容量与肺活量比率及平均气流率做为衡量嗓音功能的临床指标均有意义。
