      With the increased use of chest computed tomography (CT) in trauma patients, providers are detecting occult pneumothoraces more frequently. While standard practice has been to place a chest tube in all patients with a traumatic pneumothorax, more recently providers are observing some hemodynamically stable patients with pneumothoraces. Prior trials have concluded that using a cut-off of pneumothoraces <35mm could predict successful observation. This study aimed to demonstrate that there is an objective measurement that can be used to determine which traumatic pneumothoraces can be safely observed without requiring placement of a chest tube.
