Certified Respiratory Therapist Practice Exam

Question: 1 / 400

What is the primary goal of chest physiotherapy?

To decrease lung capacity

To mobilize secretions and improve ventilation

The primary goal of chest physiotherapy is to mobilize secretions and improve ventilation. This practice is designed to enhance airway clearance, making it easier for patients to expel mucus and other secretions from the lungs. By improving mucus clearance, chest physiotherapy helps to facilitate better oxygen exchange and overall lung function, which is particularly beneficial for individuals with conditions such as chronic obstructive pulmonary disease (COPD) or cystic fibrosis.

Techniques involved in chest physiotherapy, such as postural drainage, chest percussion, and vibration, aim to loosen and remove trapped secretions in the airways, thus improving ventilation and reducing the risk of infections caused by retained mucus. The primary focus is on enhancing respiratory mechanics and optimizing respiratory health, rather than manipulating lung capacity, carbon dioxide levels, or airway resistance.
