Background: Oxygen saturation (SpO2) is often overestimated in darker skinned individuals (1–3), but the ideal method to quantify this phenomenon and measure its impact on clinical outcomes is unclear. Studying the distributions of SpO2 may not be the appropriate method because these distributions are influenced by clinicians’ real time efforts to maintain SpO2 in a [...]
