Users are shown how to measure their own lung volumes and capacities, using spirometers and vitalographs, and compare these with accepted norms. Using interactive STPD calculations they can see how these measurements vary according to changes in ambient temperature and pressure. Other features include an interactive nomogram which highlights the variations due to age, height and gender.
