Abstract

To evaluate the reliability of the Nellcor N200 pulse oximeter in the detection of hyperoxemia (oxygen tension > 80 mm Hg), we obtained 213 simultaneous recordings and measurements of transcutaneous oxygen saturation (SO2) and arterial oxygen tension (PaO2) in 50 patients. During 95% of measurements with PaO2 > 80 mm Hg, SO2 was > or = 96%; SO2 was also > or = 96% in 20% of measurements with PaO2 < or = 80 mm Hg (false-positive results for hyperoxemia). With the upper alarm limit set at 95%, the pulse oximeter identified 95% of hyperoxemic instances while allowing PaO2 to be kept to > 60 mm Hg.

摘要

为评估Nellcor N200脉搏血氧仪检测高氧血症（氧分压>80mmHg）的可靠性，我们对50例患者同时进行了213次经皮血氧饱和度（SO2）和动脉血氧分压（PaO2）的记录与测量。在95%的PaO2>80mmHg测量中，SO2≥96%；在20%的PaO2≤80mmHg测量中，SO2也≥96%（高氧血症假阳性结果）。将上限报警值设定为95%时，脉搏血氧仪识别出95%的高氧血症情况，同时能使PaO2保持>60mmHg。
