What is the primary purpose of chest physiotherapy in respiratory care?

The primary purpose of chest physiotherapy in respiratory care is to enhance lung clearance and reduce the risk of pneumonia. This technique involves various methods such as postural drainage, percussion, and vibration, which are designed to help mobilize and clear secretions from the airways. By effectively clearing mucus and other secretions, chest physiotherapy can improve ventilation, reduce the likelihood of infection, and ultimately enhance overall respiratory function.

While strengthening respiratory muscles and preparing patients for intubation are important aspects of respiratory care, they are not the main focus of chest physiotherapy. Similarly, although increasing oxygen levels in the blood is a crucial goal in managing respiratory conditions, chest physiotherapy specifically targets the removal of secretions. Therefore, the correct choice highlights the primary intent behind this therapeutic intervention in maintaining respiratory health and preventing complications such as pneumonia.
