NCT ID NCT06586918
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This completed study looked at whether a new feature on a pulse oximeter (called perfusion index) can accurately measure blood flow in the skin. Researchers compared it to a laser Doppler device in 32 healthy adults. The goal was to see if the two methods agree, which could help doctors monitor blood flow more easily in the future.
