New light device could replace invasive fluid monitoring in ICUs

NCT ID NCT07298720

First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study tests whether a non-invasive light-based device can predict how ICU patients respond to fluids. Researchers will shine light on the arm muscle to measure blood flow and oxygen, then compare it to standard invasive monitoring during a leg-raising maneuver. If successful, this could reduce the need for invasive catheters.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

What this could lead to
If successful, this could lead to a non-invasive way to guide fluid treatment in critically ill patients, reducing the need for invasive monitoring.
What could go wrong
This is an early observational study, not a treatment trial. The device may not reliably predict fluid response, and results may not apply to all ICU patients.
