The first result shown is Peak Expiratory Flow (PEF). The arrows
indicate that the up and down keys may be used to scroll through
the other results of the test.
These include FEV1, FVC, FEV1/FVC (shown as FEV1 FVC), followed
by the percentage of predicted value for all of the above.
Note: if the unit has been previously configured with SPCS, the
displayed results will be limited to only those previously set.
However, regardless of the measurements displayed, all
measurements (including expiratory Flow/Volume and Volume/Time
data) will be recorded.
As well as the spirometry results, warning lights will also be
displayed as described in the section ’Spirometry Operation (Single
patient use)’. However, in the case of multiple patient use, the light
activation is based upon the percentage of the predicted value as
personal best values cannot be entered.
After completing a spirometry manoeuvre the user may press ‘enter’
to repeat or ‘off’ to finish testing. After completing a sequence of
tests, the best result will be stored. The definition of best is
selected using SPCS and may be best FEV1, best FVC, best PEF, or
best FEV1+FVC. When off is pressed, the user has the option to
obtain a printout of the results.
The display will change to:
