Pulse oximeters: Does skin colour affect SpO2 measurements?
A pulse oximeter is placed in the hand of a COVID-19 patient. A team of researchers from the University of Nottingham (UoN) have developed a laboratory-based test to assess the performance of POs under the effects of varying melanin (pigment responsible for colour) concentration and oxygen saturation (SpO2) values. | Photo Credit: File photo Given…
