Asthma is a disease that causes breathing difficulty due to inflammation of the air passages in the lungs that allow oxygen to the body. This causes coughing, wheezing and shortness of breath. Types of asthma include bronchial asthma and exercise-induced asthma. A nebuliser or inhaler provides relief from breathing difficulties by reducing the inflammation and expanding the constricted air passages. Left untreated, asthma can affect normal daily activities, and can be life threatening.
A spirometry test measures how well your lungs work. They measure how well you’re able to breathe and how effective your lungs are able to bring oxygen to the rest of your body.
