The incidence and the causes of the abnormal blood gas levels were analysed with 188 patients who had one lung ventilation during general anesthesia, and the monitors to detect such complications were discussed. Abnormal blood gas levels were detected in 47 patients (25%), and 6 of 47 patients had dislocation of endotracheal tube or cuff. There was one patient who suffered from severe blood gas disorder due to the total occlusion of trachea by cuff herniation. Forty one cases (41.8%) had abnormal blood gas levels even though there was no dislocation of endotracheal tube or cuff. In these patients the blood gas abnormalities were mild and transient. These data suggest that mild blood gas disorders were relatively easily detected with pulse oximeters and capnography. However, serious disorders were not detected with these monitors if the anesthesiologists were not familiar with these equipment.
对188例全身麻醉期间进行单肺通气的患者的血气水平异常发生率及原因进行了分析，并对检测此类并发症的监测器进行了讨论。47例患者（25%）检测出血气水平异常，47例中有6例气管导管或套囊移位。有1例患者因套囊疝导致气管完全阻塞而出现严重血气紊乱。41例（41.8%）患者即使气管导管或套囊未移位也出现了血气水平异常。在这些患者中，血气异常较轻且为一过性。这些数据表明，使用脉搏血氧仪和二氧化碳监测仪相对容易检测到轻度血气紊乱。然而，如果麻醉医生不熟悉这些设备，则无法通过这些监测器检测到严重的紊乱情况。
