Pulmonary - Pneumothorax Lung Point

Decreased lung slide is highly sensitive, it lacks specificity. Lung point however, is a highly specific finding indicating a pneumothorax. Lung point indicates the transition point between normal pleura with normal lung sliding and where there is air disrupting the pleural space with decreased lung sliding. In this intercostal space, one can see lung with normal lung slide on the left, and decreased lung slide on the right, and a point where the lung slide changes, which is moving with inspiration. This is the lung point. Dr. Justin Bowra et al.
