摘　　要：３１例肺肿瘤患者在接受纤维支气管镜检查术中用脉搏血氧饱和度仪进行血氧饱和度（ＳｐＯ２）监测，探讨ＳｐＯ２变化的影响因素及纠正低氧血症的方法。检查中ＳｐＯ２低于检查前及对照组（Ｐ＜０．０１），这与患者术前基础肺功能减损及气道阻塞通气量降低有关。术中采用鼻导管或经纤支镜钳检孔置入导管，给氧后ＳｐＯ２可恢复到检查前水平。结果提示肺肿瘤伴有肺功能减损者术中应监测ＳｐＯ２并常规给氧，对防止或纠正低氧血症的发生或发展，增加检查术中的安全性有一定作用。The changes of pulse oxygen saturation of haemoglobin (SpO_2) and methods of oxygen supplement during fiberoptic bronchoscopy (FOB) were studied in 31 patients with lung cancer. SpO_2 was continuously monitored during FOB. SpO_2 mean values of the FOB group were significantly lower than the values of the pre-bronchoscopy and control groups(P<0.01).Hypoxemia was caused by airway obstruction and depressed ventilation,which are associated with impaired pulmonary function. Patients having oxygen supplements through a nasal catheter or a samall catheter inserted into the working channel of the fiberscope displayed a significant rise in SpO_2 values. In conclusion,oxygen supplements should be administered during FOB to patients with impaired pulmonary function,so as to prevent complications and increase the safety of FOB.
