When the stacked volume test begins, the Analyzer switches into Inspiratory Only
breath-detect mode. At the end of the test, the breath-detect mode is restored to its
previous state. The stacked volume test reports five values to the user; they are
updated every time a breath is detected:
Total Volume –the total of the tidal volumes for the breaths tested
Last Volume –the tidal volume for the last breath
Average Volume – the average tidal volume over the breaths that have been tested and
calculated
Number of Breaths – the number entered at the start of the test; it does not change during
a test.
Breath Count –the current number of breaths included in the test; if tidal volume can't be
calculated for a breath, that breath and volume are not included in the test.
