Join Nadia Jensen, RCP, RRT, Respiratory Case Manager, and Jamie Balius, RCP, Respiratory Coordinator, for an explanation of COPD, respiratory health, how to manage your medications and why you should have a spirometry test – the most common test of lung and/or pulmonary function which measures the amount of air that a person can blow out of their lungs. Spirometry is an important tool for diagnosing certain respiratory conditions, such as asthma or other lung disorders, and for monitoring lung function changes over time.
