A smartphone camera may help emergency doctors spot severe breathing trouble — a trial puts it to the test

NCT ID NCT07726628

First seen Jul 24, 2026 · Last updated Jul 24, 2026

Summary

This trial tests whether adding a live video feed from a caller's smartphone camera to standard phone triage helps emergency doctors make better decisions for adults with sudden breathing difficulty. About 778 adults who call a French emergency medical center for acute shortness of breath will be included. The goal is to see if video-assisted triage reduces both under-triage (missing a serious case) and over-triage (sending too many resources).
