FLOW ERROR
If the last flow point of the F/V curve is greater than 200 mL/s, this indicates that the
expiration was not complete and thus the following comment is shown:
BLOW OUT ALL AIR IN LUNGS
Between two tests, spirobank G evaluates the repeatability of the following parameters:
PEF repeatable when the difference between the two largest PEF is ≤ 0.67 L/s;
VC repeatable when the difference between the two largest VC is ≤ 150 mL;
If FVC is > 1.0 L then:
FEV1 repeatable when the difference between the two largest FEV1 is ≤ 150 mL;
FVC repeatable when the difference between the two largest FVC is ≤ 150 mL;
if FVC is ≤ 1.0 L then:
FEV1 repeatable when the difference between the two largest FEV1 is ≤ 100 mL;
FVC repeatable when the difference between the two largest FVC is ≤ 100 mL;
2.8.6 Viewing the spirometric parameters
I° case: ATS/ERS standard
Following an FVC test, the spirometry test results are shown. The first screen displays the
main parameters *FVC, *FEV1, *PEF, *FEV1%,, the percentage of the predicted values
(or of the PRE values in the case of a POST phase), the Flow/Volume curve plus a traffic
light summary of the test interpretation (in the upper right), as illustrated below.

In case of “repeatability” a symbol ® is shown in the graphic area
The following screens show other values compared to the predicted values (or to the PRE
values if is a POST phase).
Parameters shown:
FVC, FEV1, FEV1/FVC, FEV1/VC, PEF, FEF2575, FEF25, FEF50, FEF75, FEV3,
