NCT ID NCT03706430
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested a new sensor measure called RPVi to see if it can predict how patients will respond to fluids during surgery. Researchers compared RPVi to standard methods in 63 adults having elective surgery. The study was terminated early, so the findings are limited.
