What describes the purpose of a low basilar chest tube?

The primary purpose of a low basilar chest tube is to remove excess fluid from the pleural space. This type of chest tube is strategically placed lower in the chest cavity to effectively target and drain fluid accumulations, such as those seen in conditions like pleural effusion or empyema. By positioning the tube in the lower part of the pleura, healthcare providers can ensure that gravity aids in the drainage process, allowing for more effective removal of fluid.

While the collection of blood from the thoracic cavity can occur, it is specifically addressed by different types of drainage systems and is not the primary intent of a low basilar chest tube. Similarly, draining air from the pleural cavity is typically facilitated through higher placement of chest tubes, and analyzing pleural effusion generally involves sampling fluid rather than actively draining it. Hence, the correct response emphasizes the tube’s role in fluid management rather than in blood collection or air removal.
