NCT ID NCT05745662
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This study tested a pulse oximeter device that measures blood oxygen and pulse rate without needles. Eleven healthy volunteers had their oxygen levels temporarily lowered in a controlled way to see how accurate the device was compared to blood samples. The goal was to check if the device works well even in very low oxygen conditions.
