Abstract

Pulse oximeters are used to noninvasively measure oxygen saturation in arterial blood (SaO). Although arterial oxygen saturation measured by pulse oximeter (SpO) is usually indicated in 1% increments, the value of SaO from arterial blood gas analysis is not an integer. We have developed a new pulse oximeter that can measure SpO to one digit after the decimal point. The values of SpO from the newly developed pulse oximeter are highly correlated with the values of SaO from arterial blood gas analysis (SpO = 0.899 × SaO + 9.944, = 0.887, < 0.0001). This device may help improve the evaluation of pathological conditions in patients.

摘要

脉搏血氧仪用于无创测量动脉血中的氧饱和度（SaO）。尽管通过脉搏血氧仪测量的动脉血氧饱和度（SpO）通常以1%的增量显示，但动脉血气分析得出的SaO值并非整数。我们开发了一种新型脉搏血氧仪，它能够将SpO测量到小数点后一位。新开发的脉搏血氧仪所测SpO值与动脉血气分析得出的SaO值高度相关（SpO = 0.899 × SaO + 9.944，r = 0.887，P < 0.0001）。该设备可能有助于改善对患者病理状况的评估。
