Continuous monitoring of arterial oxygen saturation and heart rate with a pulse oximeter was performed in 100 consecutive patients undergoing esophagogastroduodenoscopy (78) or colonoscopy (22). Twenty-four patients had decreases in their estimated arterial PO2 level to less than 60 mm Hg during or just after the procedure. In 15 patients the hypoxemia was transient, but in nine others, treatment was required. Twenty patients also developed a tachycardia greater than 120 beats/minute.
对连续100例接受食管胃十二指肠镜检查（78例）或结肠镜检查（22例）的患者，使用脉搏血氧仪持续监测动脉血氧饱和度和心率。24例患者在检查期间或检查刚结束时，估计动脉血氧分压水平降至低于60mmHg。15例患者的低氧血症是短暂的，但另外9例患者需要治疗。20例患者还出现了心率超过120次/分钟的心动过速。
