This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.

Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.

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.

This is an AI summary of the original study and may miss details. Read our disclaimer.
