可采用较低氦浓度的氦氧混合气体对慢阻肺患者进行氧疗或康复治疗。
It is suggested that helium-oxygen mixture with lower helium concentration can be used in oxygen therapy or rehabilitation therapy in COPD patients and decrease its clinical costs.
比较含80%氦和含60%氦的氦氧混合气体对肺活量及其相关指标的影响。
To compare the effect of helium-oxygen mixtures containing 80%helium or 60%helium on vital capacity(VC) and related index.
目的：比较含80%氦和含60%氦的氦氧混合气体对肺活量及其相关指标的影响。

结果呼吸含60%氦的氦氧混合气体后，肺活量、补呼气容积呈大幅增加，深吸气量呈轻微下降变化，其中补呼气容积前后变化具有显著差异（P<0.05）。
Results: After breathing He-O2 containing 60% helium, VC and ERV increased enormously, while IC decreased mildly, among which the change of ERV showed significant difference (P<0.05).
我很惊讶地发现当使用混合气体(氮氧或氦氧)时耗气量没有作为氮气吸收的一个指标。
I was surprised to notice that air consumed is not used as a factor for nitrogen absorbed when the type of air mixture (nitrox or heliox) is.
