Accuracy of Pulse-Oximetry in Non-white Patients.

Pulse oximeters are widely used to monitor saturation of peripheral oxygen (SpO2) in the clinical setting. Patients with dark skin pigmentation are at risk for hidden hypoxemia due to overestimation of SpO2 compared to true arterial oxygen saturation resulting from melanin absorption of the red and infrared light sources. Clinicians must be aware of this potential inaccuracy when interpreting SpO2 value, considering the overall assessment of the patient.

Ongoing improvement of current and emerging oxygen monitoring technology is essential to improve accuracy and equitable care for all patients.
