a.
To describe: The effects of a large open pneumothorax on the respiratory function and on the cardiovascular function.
Concept introduction: The existence of air or gas in the pleural space caused by a rupture in the visceral pleurae or the parietal pleurae and the chest wall is known as the pneumothorax. It further leads to an accumulation of fluid in the lungs. Usually, air separates the parietal and visceral pleurae and it destroys the negative pressure of the pleural space as well as it interrupts the equilibrium between the chest wall and the elastic recoil forces of the lungs.
b.
To explain: The way in which the covering of an open pneumothorax improves oxygen levels.
Concept introduction: The existence of air or gas in the pleural space caused by a rupture in the visceral pleurae or the parietal pleurae and the chest wall is known as the pneumothorax.

c.
To explain: The possible cause of increased respiratory distress following the covering of an open pneumothorax.
