In the EXAKT study from the U.K., the home-use pulse oximeters assessed all gave higher oxygen saturation (SpO2) readings for patients with darker skin tones than for patients with lighter skin tones.

SpO2 readings were, on average, 0.6-1.5 percentage points higher for patients with darker than lighter skin tone. At both SpO2 thresholds assessed, false negative rates (low oxygen missed by the pulse ...

Fingertip monitors known as pulse oximeters that can be used at home to detect low blood oxygen levels (hypoxaemia) give higher readings for patients with darker than lighter skin tones, finds the ...

SpO 2 readings were—on average—0.6–1.5 percentage points higher for patients with darker than lighter skin tone. At both SpO 2 thresholds assessed, false negative rates (low oxygen missed by the pulse ...
