可能影响危重患者脉搏血氧饱和度（SpO（2））记录准确性的变量的影响尚未得到很好的确定。我们试图描述成人重症监护室（ICU）患者成对SpO（2）/SaO（2）（通过动脉血气分析的氧饱和度）之间的关系，并描述SpO（2）在检测低SaO（2）和PaO（2）方面的诊断性能。对ICU中的404名成人进行成对SpO（2）/SaO（2）测量。测量用于计算偏倚、精密度和一致性限度。偏倚和变量之间的相关性包括血管加压药和正性肌力药的使用、毛细血管再充盈时间、手温、脉压、体温、血氧计型号和肤色。配对SpO（2）/SaO（2）测量值没有总体统计学显著偏倚;观察到的一致性限度为+/-4.4%。然而，体温、血氧计型号和肤色与偏倚程度有统计学显著相关性。SpO（2）
The influence of variables that might affect the accuracy of pulse oximetry (SpO(2)) recordings in critically ill patients is not well established. We sought to describe the relationship between paired SpO(2)/SaO(2) (oxygen saturation via arterial blood gas analysis) in adult intensive care unit (ICU) patients and to describe the diagnostic performance of SpO(2) in detecting low SaO(2) and PaO2. A paired SpO(2)/SaO(2) measurement was obtained from 404 adults in ICU. Measurements were used to calculate bias, precision, and limits of agreement. Associations between bias and variables including vasopressor and inotrope use, capillary refill time, hand temperature, pulse pressure, body temperature, oximeter model, and skin colour were estimated. There was no overall statistically significant bias in paired SpO(2)/SaO(2) measurements; observed limits of agreement were +/-4.4%. However, body temperature, oximeter model, and skin colour, were statistically significantly associated with the degree of bias. SpO(2)
