Spirometry Extension: Chart 5 for Windows

Go to ADResearch Go to ADEducation Go to ADPharma

Spirometry is a Chart extension used to derive a number of respiratory parameters based on flow and volume. These include VE, VT, frequency, PIF, PEF, FVC, FEV1. The Spirometry Extension also generates a flow-volume plot and spirometry reports. This extension is designed for both teaching and research, not for clinical diagnostic purposes.

Spirometry v2.0 requires Chart v5.4 or later. We recommend that all users update to Spirometry v2.0.

Spirometry v2.0 is compatible with existing Chart data files. Spirometry v2.0 settings are not backwards compatible, files with settings created by Spirometry v2.0 cannot be loaded using earlier versions of Spirometry.

Spirometry is available to download as an installer from the Extension File link below. The installer will put the extension into the Chart Extensions folder and the Users Guide into the Documentation folder.

For additional information about installing extensions see the Downloading and Installing Chart Extensions for Windows page.

Downloading of resources is free to PowerLab users but requires a password. If you do not have a password register here.

To find out if your computer is able to use Spirometry, visit the ADInstruments Software system requirements page.
