RationalePulse oximeter performance may vary by skin pigmentation, but most data are retrospective with key limitations. ObjectiveTo quantify pulse oximeter bias [mean difference between pulse oximeter oxygen saturation (SpO2) and arterial blood functional oxygen saturation (SaO2)], and average root mean square error (ARMS) and estimate adjusted effects of skin pigment on bias or ARMS in critically-ill adults MethodsProspective single-center study of 631 ICU patients (2022-2024) directly obser...
