The Spirocomp Command Window displays important information about the database, notes or comments for the current record, and allows quick access to software features.

This analysis view clearly depicts the relationship between each of the measured and computed lung volumes. The vital capacity bar can be toggled to display a stack of its component volumes or the fraction of air expelled within the first second (FEV1).

When acquiring data, a volume gauge appears on the left, and the subject is prompted as to how to proceed. A text prompt appears on the status line at the bottom of the window, and audio prompts can be heard (if enabled in preferences).

Volume is graphed against time during the measurement of vital capacity. Afterwards, a data marker can be positioned anywhere along the curve to determine the volume of air expelled at any time during the forced expiratory effort. This makes it possible to quantify such parameters as FEV and mid expiratory flow. In addition, the shape of the curve itself can be compared between various subjects and its physiological significance explored.

The Summary Table displays all the data from the database in spreadsheet format. This same data can also be dumped (exported) to a text file and then imported into another application for further analysis.
