【摘要】 本文报道了２８８例１４～８６岁患者纤支镜检查前、中、后的连续血氧饱和度（ＳａＯ２）及心电监测结果。术前平均ＳａＯ２为９７．１７％。检查组术中平均降低２．０９％，术后５分钟较术前降低１．７％。治疗组术中ＳａＯ２平均降低２．４３％，术后５分钟较术前降低３．４３％。术中心电图改变以窦性心动过速为主，占６２％，原心电图不正常者术中心律失常加重为７％，原无心律失常者术中心律失常出现率为１．Ｏ％。由于纤支镜检术中抽查血气不便，我们认为无创的血氧饱和度、心电动态监测不失为一简单易行，可靠的监测手段。更多还原

【Abstract】 In this article,we discuss the results obtained from consecutive observations of electrocardiogram and SaO2 saturation based on 288 aged of patients were patients before,during and after diagnostic Fiberoptic Bronchoscope. The ages of patients were 14～86 years old Among the examined group,the average SaO2 of subjects before diagnosis is 97. 17%;during the diagnosis the SaO2 of subjects decrease 2. 09%;five minutes after examinations the SaO2 of subjects is 1.7% lower than that before the examinations. Among the treatment group ,the average SaO2 decreases 2.43%. Five mintes after examination, it is 3. 43% lower than that before examinations. During the examination, the changes of electrocardiograms are mainly caused by sino-auricular tachycadia which is 62% of the whole changes. Seven per sent of subjects whose electrocardiograms are abnormal undergoes worse abnormal rhythm of heart.1.0% of normal-electrocardiogram-patients is reported abnormal heart-beating. Since it is inconvenient to evaluate(test) the hemopneumo,we believe that motive non injury observation of electrocardiogram and SaO2 is a simple and reliable testing method.更多还原
