摘　　要：气管内吸引易引起缺氧,其安全时限尚无统一标准。我们用无创性脉搏血氧饱和度仪持续监测气管内吸引时血氧饱和度(SpO_2)变化。结果:SpO_2下降幅度随吸引时间延长而增大。为避免缺氧,对于有自主呼吸的患者,吸引时间不宜超过30s,无自主呼吸的患者,不宜超过20s。Tracheal suction could cause hypoxia, bt there was not a consistent of safe time during tra- cheal suction. We continously monitored the xhanges of the SpO_2 by using pulse oximeter during tracheal suc- tion. The results indicated that the longer the suction time the lower the SpO_2. Tc avoid hypoxia during tra- cheal suction, some safe measures were proposed. The paper suggested that the suction time should be less than 30 seconds for patients with autonomous respiration and it should be less than 20 seconds for patients with apnea.
