First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested whether measuring pulse volume in the leg can help doctors detect active bleeding during an endoscopy for gastrointestinal bleeding. Researchers used a non-invasive pulse flowmeter on 13 adults undergoing emergency endoscopy. The goal was to see if changes in pulse volume could predict active bleeding or high-risk signs.
What this could mean

- What this could lead to
- If this approach works, it could give doctors a non-invasive way to spot active bleeding during endoscopy.
- What could go wrong
- This was a very small, early feasibility study with only 13 participants. The method may not be accurate enough for routine use.
