First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
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.
