pulmonary capacity

Objective: To discuss the difference of vital capacity ( VC), expiratory reserve volume ( ERV) and inspiratory capacity ( IC) in chronic obstructive pulmonary disease ( COPD) patients and the normal subjects after breathing helium-oxygen mixtures ( heliox).

目的探讨慢性阻塞性肺病（COPD）患者呼吸氦氧混合气（He-O2）后肺活量（VC）及其组成补呼气容积（ERV）和深吸气量（IC）的变化与健康人的差异。

Diffusion capacity ( DLco) of 315 asbestos workers without obvious radiological pulmonary changes and 314 healthy workers without history of exposure to industrial dust as controls were measured by means of CO single breath technique.

本文采用一次呼吸CO法，测定了315名石棉工人和314名作为对照的不接尘健康工人的弥散量，并测定了通气功能。

Objective: To assess the changes of the membrane diffusing capacity ( Dm) and pulmonary capillary blood volume ( Vc) in different stages of COPD and the effect of the bronchodilator inhalation on diffusing capacity ( DLCO) and Dm in COPD patients.

目的：探索慢性阻塞性肺疾病（COPD）缓解期不同分级的患者膜弥散功能（Dm）和肺血管床容量（Vc）的变化，以及使用支气管扩张剂后通气功能改善对Dm和Vc的影响。

Their average pulmonary capacity and pulmonary/ body weight were not improved, except the vital capacity of the Sala male students, and trended to decrease to a great extent.

3）在机能方面，肺活量和肺活量/体重指标（除撒拉族男生肺活量外）平均增长值均为负，呈现出较大幅度的下降趋势。

Pulmonary function: Compared with that before exercise, the maximal ventilatory capacity MVV increased by 11%.

肺功能：与锻炼前相比，最大通气量增加11%；
