NCT ID NCT07303972
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study will test a new way to measure blood flow in the lungs using a belt that sends weak electrical currents and small injections of salt water. One hundred healthy adults will hold their breath at two different lung volumes while the device creates a map of blood flow. The goal is to see how lung inflation changes blood distribution, which could help doctors better manage breathing machines for patients with lung problems.
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 improve how doctors monitor lung function and tailor breathing support for patients with lung disease.
What could go wrong
This is a small, early-stage observational study in healthy volunteers, so results may not apply to sick patients. The technique is still experimental.
