FDA advisers meet on racial disparities in pulse oximeters
The clip-on devices that use light to measure oxygen levels in the blood are getting a closer look from U.S. regulators after recent studies suggest they don’t work as well for patients of color
NEW YORK (AP) — The clip-on devices that use light to measure oxygen levels in the blood are getting a closer look from U.S. regulators after recent studies suggest they don't work as well for patients of color.
The devices, called pulse oximeters, usually snap onto a finger and are widely used in hospitals across the globe to help guide treatment. At-home versions became popular during the COVID-19 pandemic.
But several recent studies have raised concerns that the pigmentation in people’s skin can throw off the readings. In 2021, the Food and Drug Administration issued a warning about possible inaccuracies after a study found the devices tended to overestimate Black patients’ oxygen levels.
“The fact that such a commonly used device could have any discrepancy at all was shocking to me,” said Michael Sjoding, a University of Michigan pulmonologist who led the study. “I make a lot of medical decisions based on this device.”
