Ultrasound may prevent wrong treatment for elderly with breathing distress
NCT ID NCT06807983
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at whether using lung and heart ultrasound can help emergency doctors give the right treatment faster to older adults (over 65) who come to the ER with sudden breathing trouble. About 504 participants will be enrolled. The goal is to see if ultrasound reduces the chance of starting a treatment that later turns out to be wrong.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: Eligible patients will be aged over 65 years, affiliated with the French social security system, and presenting to the ED with acute dyspnea (onset \<14 days) accompanied by severity signs before or at triage (respiratory rate ≥22 and SpO2 \<92% on room air). The enrolling emergency physician (EP) must be the patient's treating physician and must be trained in LuCUS. Written informed consent from the patient or their legal representative is required for inclusion Exclusion Criteria: dyspnea secondary to thoracic trauma, dyspnea clearly related to COVID-19, known pulmonary fibrosis or lung cancer, prior administration of specific treatment for dyspnea before inclusion, immediate need for endotracheal intubation, patients identified as being at end-of-life, and individuals under legal guardianship or deprived of liberty.
