Pulse oximeters rose to prominence bc they OVERestimated oxygen in patients with darker skin tones during the pandemic Now they seem to be UNDERestimating oxygen levels... What's happening? We still don't know but it could point to deeper issues w/ the devices www.statnews.com/2026/10/06/p...

In this hospital, pulse oximeters went from overestimating to underestimating blood oxygen. Why?

Researchers found pulse oximeters went from overestimating blood oxygen levels to underestimating them; inaccuracies were worse in patients of color.

Performance Inconsistency of Pulse Oximeters Over Five Years of Clinical Use: A Single-Center Study of Masimo Devices - PubMed

The accuracy of the tested medical-grade pulse oximeter changed year-to-year at a large hospital compared to concurrent arterial blood gas saturation, potentially complicating safe clinical decision-making and application of evidence-based medicine. Errors of false hypoxemia became more common, thre …

There’s been some “advice” coming from some quarters for scientists not to focus on DEI-related funding cuts. I wholly reject this concept. Cutting programs designed to reduce science and healthcare disparities is as detrimental to science as anything else, both morally and functionally.

Pulse oximeters performed poorly in children with objectively brown or dark skin tone and, importantly, did not even meet FDA standards for *overall* accuracy even though only 4% of the study sample had dark skin tone. This reiterates our finding in a pilot study of adults showing that.... #MedSky

Simultaneous measurements in children revealed overestimation of arterial saturation by pulse oximetry that was attributable to spectrophotometric measures of skin tone. Learn more: nej.md/4hyuZ1B #MedSky #PedSky
