Spirometry

Spirometry is a tool that measures how effectively your lungs are working. It is able to show how much air lungs are able to hold (their volume) and how much air can be breathed in and out (inhaled and exhaled) which is called flow. This tool is used to assess damage caused by conditions like COPD (chronic obstructive pulmonary disease – a group that includes bronchitis and emphysema), pulmonary fibrosis, cystic fibrosis and asthma. Results are shown on a graph called a pneumotachograph.
