Pulse oximeters may be less accurate on darker skin – study investigates
NCT ID NCT07415187
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study looks at whether pulse oximeters, which measure blood oxygen through the skin, are less accurate in people with darker skin. Researchers will compare readings from two common oximeters with oxygen levels measured directly from blood in 194 hospital patients. The goal is to understand if skin tone affects accuracy and to help make these devices safer for everyone.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- What this could lead to
- If this study finds clear differences, it could lead to better pulse oximeters that work accurately for all skin tones, improving patient safety.
- What could go wrong
- This is an observational study, not a treatment trial. It only measures accuracy and won't directly fix any problems found. Results may not apply to all devices or settings.
