What is the role of bronchodilators in respiratory therapy?

The role of bronchodilators in respiratory therapy is to improve airflow through the bronchi. Bronchodilators are medications that relax and open the airways in the lungs, allowing for easier breathing. They work by dilating the bronchial passages, which helps reduce symptoms of respiratory conditions such as asthma and chronic obstructive pulmonary disease (COPD). By widening the airways, bronchodilators enhance airflow, enabling patients to breathe more freely and efficiently. This is crucial for individuals facing difficulty in their respiratory function, as improved airflow directly contributes to better oxygen exchange and overall respiratory health.
