Prehospital Use of Ultrasound in Undifferentiated Shortness of Breath

Completed

Conditions studied: Pneumonia, Pulmonary Edema, Dyspnea

In brief

This is a pilot observational feasibility study of the ability of paramedics to assess thoracic ultrasound findings in the prehospital environment. The primary goal of the study is to determine whether paramedics are able to accurately assess for sonographic B-lines in patients with undifferentiated shortness of breath at least 80% of the time in the prehospital environment using a portable ultrasound (U/S) device.
