本研究的目的是评估动脉血氧饱和度和脉搏血氧饱和度值之间的一致性，特别是在低氧条件下，并测试该方法在常规麻醉条件下的适用性。我们研究了13例先天性紫绀型心脏病患者（12例儿童，1例成人）; 12例在非搏动性体外循环期间进行了手术矫正，1例进行了姑息性手术。在麻醉诱导、手术期间以及某些情况下在术后期间同时进行动脉血氧计和脉搏血氧计测量并进行比较。通过Ohmeda Biox 3700脉搏血氧仪记录脉搏血氧仪饱和度值，并通过CO血氧仪（OSM 2血氧仪，辐射计）测定相应的动脉饱和度。这些值在43%-100%的动脉血氧饱和度范围内。在考虑稳态和非稳态情况（即，当脉搏血氧饱和度读数快速变化且难以按时间协调比较动脉测量时），以及设备的信号质量内部表征（高质量信号（HQS）/低质量信号（LQS））。在稳态和非稳态条件下，所有比较测量的相关性分析结果为r = 0.927。当比较仅限于稳态条件下的测量值时，结果为r = 0.935。脉搏血氧饱和度值有低于相应动脉值的趋势。脉搏血氧饱和度值被指定为HQS或LQS的事实并不表明与动脉值的相关性更好或更差。（250字处删节）
The aim of this study was to evaluate the agreement between arterial and pulse oximeter saturation values, especially under hypoxemic conditions, and to test the applicability of the method under routine anesthesia conditions. We studied 13 patients (12 children, 1 adult) with congenital cyanotic heart defects; 12 had a surgical correction during nonpulsatile cardiopulmonary bypass and 1 had a palliative operation. Arterial and pulse oximeter measurements were simultaneously taken and compared during induction of anesthesia, surgery, and in some cases during the postoperative period. Pulse oximeter saturation values were recorded by an Ohmeda Biox 3700 pulse oximeter, and the corresponding arterial saturations determined with a CO Oximeter (OSM2 Hemoximeter, Radiometer). The values lay in the range of 43%-100% arterial oxygen saturation. The results were evaluated while taking into account the steady state and non-steady state situations (i.e., when there were rapidly changing pulse oximetric saturation readings and difficulties in coordinating the comparative arterial measurements time-wise), as well as the equipment's internal characterization of the signal quality (High Quality Signal (HQS)/Low Quality Signal (LQS]. The correlation analysis for all comparative measurements, under both steady state and non-steady state conditions, gave a result of r = 0.927. When the comparison was restricted to the measurements in the steady state conditions, r = 0.935 resulted. The pulse oximetry saturation values had a tendency to lie below the corresponding arterial values. The fact that the pulse oximetry values were designated with HQS or LQS was no indication of a better or worse correlation with the arterial value.(ABSTRACT TRUNCATED AT 250 WORDS)
