Pulse oximeter accuracy put to the test in motion study
NCT ID NCT04814342
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This study checked how well a pulse oximeter (a device that shines light through the skin to measure blood oxygen) works when people are moving and have very low oxygen levels. Five healthy adults had their oxygen levels temporarily lowered while using the device. The goal was to see if the readings matched those from blood samples and heart monitors.
