In the News: The Fatal Flaw of the Pulse Oximeter (6/24/22)
Dr. Govind Rao was quoted in an June 2022 article by Rebeca Sohn for IEE Spectrum for the Technology Insider titled "The Fatal Flaw of the Pulse Oximeter Racial bias led to faulty product design that led to its inability to work properly with melanin-rich skin".

The study “shows how urgent it is to move away from pulse [oximeters],” said Rao, and to find alternatives ways of measuring blood-oxygen saturation.

A long-term solution will require changing the technology, either by using a different method entirely or having devices that can better adjust results to account for differences in skin color. One technological alternative is having devices that measure oxygen diffusing across the skin, called transdermal measurement, which Rao’s lab is working on developing.
