Mr. b came in to the er with two broken ribs and a punctured lung. why did they have to insert a chest tube into his pleural space

Mr. B developed a neumotorax, therefore doctors inserted a chest tube to alleviate the pressure.

Explanation:

When a lung is punctured, air flows into the pleural space and because of the pressure it generates, it does not allow for the lung to expand normally. In this case, is best to insert a tube that enables air to leave the cavity and alleviates the pressure on the lung. In this way the lung can expand properly again.
