In the context of respiratory therapy, what does the term 'rescue medication' typically refer to?

In respiratory therapy, the term 'rescue medication' refers specifically to medications that provide immediate relief from acute symptoms of respiratory distress, such as sudden wheezing, shortness of breath, or asthma attacks. These medications, such as short-acting bronchodilators, work quickly to open airways and alleviate symptoms that arise from bronchoconstriction.

The primary purpose of rescue medications is to offer fast-acting relief during a respiratory emergency, making them essential for individuals with reactive or obstructive airway diseases. They are distinct from long-term control medications, which are used to manage ongoing conditions and prevent future attacks, and are not intended for immediate symptom relief in acute situations. Therefore, understanding the role of rescue medications is crucial for effective respiratory management, as they are lifelines during exacerbations of respiratory conditions.
