<P> In physiology , intrapleural pressure ( also called intrathoracic pressure ) refers to the pressure within the pleural cavity . Normally , the pressure within the pleural cavity is slightly less than the atmospheric pressure , in what is known as negative pressure . When the pleural cavity is damaged / ruptured and the intrapleural pressure becomes equal to or exceeds the atmospheric pressure , pneumothorax may ensue . </P>
