报告60例胸腔积液及70例胸膜粘连增厚患者肺功能及动脉血气结果.胸腔积液对肺功能及动脉血氧分压(PaO_2)影响取决于积液量.大量积液对肺功能影响极严重,肺活量占预测正常值54.2%;用力肺活量占56.9%;第1秒用力呼气量占48.5%;肺总量占62.9%;PaO_2占78.1%.胸膜粘连增厚对肺功能损伤类型与胸腔积液相同,损伤程度位于大、中量积液之间. The report of 60 cases of pleural effusion and 70 cases of pleural thickening in patients with pulmonary function and arterial blood gas results.Effects of hydrothorax on pulmonary function and arterial partial pressure of oxygen (PaO_2) depends on the fluid volume.Large effusion on pulmonary function Extremely severe, vital capacity accounted for 54.2% of predicted normal; forced vital capacity accounted for 56.9%; first forced expiratory volume 48.5%; total lung accounted for 62.9%; PaO_2 accounted for 78.1%. Pleural adhesion thickening of lung function damage type and The same pleural effusion, the degree of damage is located in between large and medium volume effusion.
