Abstract

An in vitro system was developed capable of testing the accuracy and reproducibility of pulse oximeter readings. The pulse oximeter probe receives signals through a pulsating blood cuvette. The development of the design of the cuvette is described. Using the final design (or 'model finger'), a comparison is made between readings from a Datex Satlite pulse oximeter (SpO2) and saturation values obtained by use of a multi-wavelength bench oximeter (SaO2). Linear regression analysis of the data gives SpO2 = 0.88 SaO2 + 11.2 (r = 0.979, p < 0.001).

摘要

开发了一种能够测试脉搏血氧仪读数准确性和可重复性的体外系统。脉搏血氧仪探头通过脉动血样杯接收信号。描述了血样杯设计的发展过程。使用最终设计（或“模型手指”），对Datex Satlite脉搏血氧仪的读数（SpO2）与使用多波长台式血氧仪获得的饱和度值（SaO2）进行了比较。对数据进行线性回归分析得出SpO2 = 0.88 SaO2 + 11.2（r = 0.979，p < 0.001）。
