New study aims to simplify ICU monitoring with pulse oximeter trick
NCT ID NCT07555041
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at two methods to check blood flow in critically ill patients: the traditional capillary refill time (pressing on skin and timing color return) and the perfusion index (a continuous reading from a finger clip). Researchers want to see if the perfusion index can replace the manual test, saving time for healthcare workers. The study will include 250 adults in the ICU.
