Oxygen monitoring devices may be unreliable in black patients, researchers say

 


Covid-19, a disease caused by the new coronavirus, can reduce blood oxygen levels to dangerously low levels, and the devices used to monitor these levels are better than white patients. Black patients were found to be much less reliable.

A pulse oximeter clips to your fingertips and passes red and infrared through your skin to measure oxygen levels in your blood. Oxygen levels get darker as they go down. Pulse oximeters were mostly tested in Caucasians at the time of development, so they are calibrated for people with light skin tones. Of the 1,609 patients studied at the University of Michigan Hospital in Ann Arbor last year, the device missed low oxygen levels in 11.7% of black patients, compared to 3.6% of white patients.
