PURPOSE: To analyse the ultrasonographic findings of community-acquired pneumonia (CAP) and its efficacy for diagnosis of CAP compared with chest X-ray (CXR). METHODS: Patients who presented to the Emergency Department with suspected CAP were included in the study. Bedside ultrasonography was performed at each intercostal space in the midclavicular, anterior axillary, midaxillary and paravertebral lines. Any pulmonary consolidation, focal interstitial pattern, pleural-line abnormalities and subpleural lesions were recorded, and the numbers of subpleural lesions and intercostal spaces with pleural-line abnormalities were counted...

We report the case of a dyspneic patient with a five-liter pleural empyema that was diagnosed and managed in a resource-limited clinic in a rural part of Sierra Leone. The diagnosis and management of this condition are usually guided by imaging modalities such as X-rays or CT scans. However, these resources may not be available in austere settings in developing countries. Because emergency physicians work in a variety of clinical settings, they should be well versed in the use of portable ultrasound machines to diagnose, treat, and manage many different conditions...

BACKGROUND: When used with standard diagnostic testing, point-of-care ultrasonography might improve the proportion of patients admitted with respiratory symptoms who are correctly diagnosed 4 h after admission to the emergency department. We therefore assessed point-of-care ultrasonography of the heart, lungs, and deep veins in addition to the usual initial diagnostic testing in this patient population. METHODS: In a prospective, parallel-group trial in the emergency department at Odense University Hospital, Odense, Denmark, patients (≥18 years) with a respiratory rate of more than 20 per min, oxygen saturation of less than 95%, oxygen therapy, dyspnoea, cough, or chest pain were randomly assigned in a 1:1 ratio with a computer-generated list to a standard diagnostic strategy (control group) or to standard diagnostic tests supplemented with point-of-care ultrasonography of the heart, lungs, and deep veins (point-of-care ultrasonography group)...

BACKGROUND: Lung ultrasound has been shown to identify in real-time, various pathologies of the lung such as pneumonia, viral pneumonia, and acute respiratory distress syndrome (ARDS). Lung ultrasound maybe a first-line alternative to chest X-ray and CT scan in critically ill patients with respiratory failure. We describe the use of lung ultrasound imaging and findings in two cases of severe respiratory failure from avian influenza A (H7N9) infection. METHODS: Serial lung ultrasound images and video from two cases of H7N9 respiratory failure requiring mechanical ventilation and extracorporeal membrane oxygenation in a tertiary care intensive care unit were analyzed for characteristic lung ultrasound findings described previously for respiratory failure and infection...
