论文摘要
研究表明，血液氧化的脉搏血氧仪的测量具有统计偏差，这是种族的函数，这会导致有色人种患者的神秘性低氧血症率更高，即缺失危险的低氧合作用。本文进一步表征了脉搏OX测量值的统计分布，这表明与种族化的患者相比，它们的种族差异也更高。我们表明，没有单一的基于种族的校正因子将在低氧血症的检测中提供同等的表现。结果对种族公平的脉搏血氧饱和度具有影响。
Studies have shown pulse oximeter measurements of blood oxygenation have statistical bias that is a function of race, which results in higher rates of occult hypoxemia, i.e., missed detection of dangerously low oxygenation, in patients of color. This paper further characterizes the statistical distribution of pulse ox measurements, showing they also have a higher variance for patients racialized as Black, compared to those racialized as white. We show that no single race-based correction factor will provide equal performance in the detection of hypoxemia. The results have implications for racially equitable pulse oximetry.
