New pulse oximeter put to the test in Low-Oxygen conditions
NCT ID NCT04814823
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This study tested how accurately a new pulse oximeter (a device that shines light through the skin to measure blood oxygen) works in 13 healthy adults whose oxygen levels were temporarily lowered. The device's readings were compared to actual blood samples and heart monitors. The goal was to see if the device gives reliable results, which could help doctors better monitor patients with breathing or heart problems.
