Abstract

Arterial blood gases are invasive and they provide intermittent information only. On the other hand, pulse oximetry is non invasive, providing continuous monitoring of SaO2 (SpO2). A study was therefore carried out in twelve patients undergoing lung and intrathoracic surgery to determine whether pulse oximetry was a reliable method of monitoring. The SpO2 values obtained using a Physiocontrol Oximeter (Lifestat 1600) were compared with those given by blood gas measurements (SaO2). When ventilation was switched to one-lung ventilation, PaO2 fell in all cases, whatever the method of monitoring, with PaCO2 remaining constant. 46 paired values of SaO2 were compared using linear regression analysis. Correlation between the two methods was good (r = 0.95; p less than 0.001). Pulse oximetry would therefore seem to provide a reliable method of continuous noninvasive and accurate monitoring of oxygenation during lung surgery.

摘要

动脉血气分析具有侵入性，且只能提供间歇性信息。另一方面，脉搏血氧饱和度测定法是非侵入性的，可连续监测血氧饱和度（SpO2）。因此，对12例接受肺部和胸腔内手术的患者进行了一项研究，以确定脉搏血氧饱和度测定法是否为一种可靠的监测方法。将使用生理控制血氧计（Lifestat 1600）获得的SpO2值与血气测量所得的血氧饱和度（SaO2）值进行比较。当通气切换为单肺通气时，无论采用何种监测方法，所有病例的动脉血氧分压（PaO2）均下降，而动脉血二氧化碳分压（PaCO2）保持不变。使用线性回归分析比较了46对SaO2值。两种方法之间的相关性良好（r = 0.95；p小于0.001）。因此，脉搏血氧饱和度测定法似乎是一种在肺部手术期间连续、非侵入性且准确地监测氧合作用的可靠方法。
