换气功能障碍

表明CTD各组均有限制性通气功能障碍和换气功能障碍。

All these showed that all of CTD groups had restrictive ventilation dysfunction and air exchange dysfunction .

肺水肿、肺萎陷以及换气功能障碍与肺泡表面活性物质（Pulmonarysurfactant，PS）减少有着密切关系。

Pneumonedema , alveolar and dysfunction of gas exchange is closely related to the decrease of pulmonary surfactant ( PS ) . Pulmonary hemorrhage and pneumonedema are the significant pathological traits of pulmonary injury in blast injury .

对慢阻肺肺心病患者换气功能障碍的探讨

Evaluation of Ventilatory Disturbances in Chronic Obstructive Pulmonary Disease-Cor Pulmonale

低肺功能患者术后换气及通气功能障碍较肺功能正常者显著（P＜0.05）。结论肺癌术后3日换气功能明显减退，尤以氧合功能降低显著。

Conclusion The gas exchange of the patients with lung caner reduced significantly in postoperative 3 days .
