Video ultrasound of spontaneous pneumomediastinum

Using the phased array probe, the subxiphoid view demonstrates normal cardiac contractility, normal chamber size, and lack of pericardial effusion. However, parasternal long, parasternal short, and apical views of the heart are of poor quality with diffuse A lines, suggesting air artifact, consistent with pneumomediastinum. The presence of bilateral lung sliding is confirmed with a linear transducer in the 2^nd intercostal spaces, thus decreasing the likelihood for a spontaneous pneumothorax.
