Summary

This study looks at whether having a remote expert guide paramedics during an ultrasound can improve diagnosis for patients with sudden breathing trouble. About 350 adults with severe shortness of breath will be split into two groups: one where the ultrasound is done with remote supervision, and one without. The goal is to see if remote help leads to more accurate diagnoses and better treatment decisions in the field.

In 175 patients ultrasound with tele-supervision and in 175 patients ultrasound without tele-supervision will be performed. Allocation to one of the two groups depends on the availability of tele-supervision. Tele-supervision is available in 50% of the time.
