Spirometry
Asthma and COPD (Chronic Obstructive Pulmonary Disease) cause problems by narrowing the bronchial tubes (or airways), resulting in shortness of breath. Narrowed airways are difficult to breathe through. The greater the narrowing, the more difficult breathing becomes. Spirometry is a test which is of great value for measuring exactly how much bronchial tubes have narrowed. The spirometer measures the speed your lungs can be filled and emptied of air, giving an indication of how well your lungs are performing. This enables your doctor to make decisions about your lung condition and to plan the best treatment for you.
