The term "pleura evac" generally refers to a drainage system used for evacuating air or fluid from the pleural cavity, which is the space between the lungs and the chest wall. This is commonly achieved through a chest tube, which is connected to a pleura-evac system. This system consists of three chambers: a suction chamber, a water seal chamber, and a drainage chamber, which collectively serve to maintain negative pressure within the pleural space and facilitate the removal of unwanted substances.

Such drainage systems are crucial in conditions where the pleural cavity is compromised, leading to respiratory distress. For example, a chest tube is often inserted when a patient has a pleural effusion (excess fluid) or a pneumothorax (accumulation of air), as these conditions can disrupt the negative pressure essential for normal lung expansion. The effective drainage helps prevent re-entry of liquid or air into the pleural space, thus stabilizing the patient's respiratory function.
