Summary
Spirometry literally means ‘measuring of breath’, and as an investigation it reflects the lung’s bellows function and can be used to determine the extent of respiratory disease.
To understand basic spirometry, we need to describe how the total space within the lungs is divided into volumes and capacities. A volume is a specific measurement of either inspired or expired gas (or in the case of tidal volume both), whereas a capacity is combination of two or more volumes.
