Spirometry2.5.3400

Turn flow and volume measurements into spirometry results with Spirometry, an ADInstruments extension that calculates respiratory values and presents them for analysis. It derives minute ventilation (VE), tidal volume (VT), breathing frequency, peak inspiratory flow (PIF), peak expiratory flow (PEF), forced vital capacity (FVC), and forced expiratory volume in one second (FEV1). This gives researchers and practitioners a way to examine respiratory behavior beyond the original flow and volume traces.

The extension also produces a flow-volume plot, allowing changes in flow to be reviewed against lung volume in graphical form. It generates spirometry reports that collect the calculated results into a suitable record for analysis or documentation. Typical uses include examining respiratory measurements in laboratory studies and reviewing data from experiments involving animals or other subjects.

The current release adds selectable flow units of uL/s, mL/s, or L/s in the Spirometry settings dialog, supporting work with smaller animals. It also adds a noise-floor clamp for the selected flow channel, which can remove small positive or negative offsets from the flow signal.

Spirometry 2.5.3400 is published for Windows on x86 architecture, so that platform and processor target should match the intended installation. Its extension format makes it suited to users who need calculated respiratory parameters, visual flow-volume analysis, and report output from flow and volume measurements rather than raw traces alone.
