Accurate pulse oximeter for dark skin color

Recent study shows consumer pulse oximeters are inaccurate for individuals with darkly pigmented skin. Researchers say that the pulse oximeters tend to overestimate the oxyhemoglobin saturation (Sao2) at low Sao2 levels.

Patients relying on just the Sao2 readings from the pulse oximeter alone i.e. SpO2 can risk missing out  treatment at crucial time due to this inaccuracy and so doctors advice giving importance to the shortness of breath and trends of pulse oximeter readings over absolute readings.

There is a need gap for pulse oximeters which can offset the bias due to skin color after further research on this subject.
