On a person of color, the pulse oximeter could indicate a patient’s oxygen levels are normal, suggesting they could be discharged home – but then their blood samples might show low oxygen levels, suggesting they not only needed additional care but also oxygen support. If the device isn’t calibrated for darker skin tones, the pigmentation of the skin could affect how the light is absorbed by the sensor, leading to flawed oxygen readings. One end of the device sends light through the finger while a sensor on the other side receives this light and uses it to detect the color of your blood bright red blood is highly oxygenated, while blue or purplish blood is less. This device is crucial in the fight against Covid.
