Spirometers are precision differential pressure transducers that are used with a PowerLab for measurements of respiratory flow rates. One of the key advantages to using LabChart in parallel with this equipment is the settings option in the free Spirometry Extension. Spirometry is a LabChart extension used to derive a number of respiratory parameters based on flow and volume including VE, VT, frequency, PIF, PEF, FVC and FEV1. Spirometry Extension provides users with a range of software presets and environmental variables that will save you the trouble of a manual calibration.
