2. Figure 1
The lung point is where the lung detaches from the inside of the chest wall. The pen-marked cross projects the position of the lung point on the patient's chest and maps the extension of the pneumothorax. The distance from the sternum to the lung point correlates with the volume of the intrapleural air.
