▲ ▼ 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.

A new non-invasive biomarker sensor from Rockley Photonics seem to address this by using infrared instead of traditional LEDs for measuring biomarkers. Since it's infrared and that the melanin pigment is invisible to it; Color of the skin is not a factor for such sensor.Upcoming wearables like smartwatches with such laser-based spectrophotometer sensors are en-route and can measure wide range of biomarkers from blood glucose to blood pressure.reply I WILL PAY FOR THAT
