Dynamic Air Bronchogram Ultrasound Sign in a Noninvasive Ventilated Patient

Abstract

Acute dyspnea is one of the most common complaints in any emergency department. Physical examination and chest radiography have been insufficient to diagnose these patients accurately and quickly. We present a clinical case of a dyspneic patient presenting to the emergency department, who was promptly diagnosed with lobar pneumonia by point-of-care pulmonary ultrasonography. This permitted the rapid onset of adequate treatment. Furthermore, we describe a dynamic air bronchogram sign in a noninvasive ventilated patient. Chest computed tomography scan was performed confirming consolidation of the middle lobe. The advent of handheld point-of-care ultrasonography is revolutionizing practical care enabling physicians with a high-accuracy, low-cost, fast, safe, and repeatable diagnostic tool.
