Pulse oximeters may be less accurate for darker skin – new study investigates
NCT ID NCT06432881
First seen Jun 26, 2026 · Last updated Jul 17, 2026 · Updated 3 times
Summary
This study looks at whether skin pigmentation affects how well Masimo pulse oximeters measure oxygen levels. Researchers will compare readings from 152 ICU patients with light and dark skin who have low oxygen levels. The goal is to see if the device works equally well 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 successful, this could improve pulse oximeter accuracy for people with darker skin, leading to better oxygen monitoring in hospitals.
- What could go wrong
- This is an observational device study, not a treatment trial. It may show differences but won't directly change patient care yet.
