Notes:
•
In the case of test types 'SVC test', 'MVV' and 'Calibration', the content of certain parameters
will differ from the conventional values. The corresponding values are noted at the end of the
table.
•
Curve data is exported in vertical format so that it can be imported to EXCEL easier.
•
Boolean values: zero designates 'False' and not equal to zero designates 'True'.
•
Suffix p: this suffix is appended to a parameter name if the test is a Post test. Example:
FEV1Best_p designates the best FEV1 value in the Post test. parameters with suffix _p exist only
if a Post test has been conducted.
•
Suffix _np: this parameter suffix is used only for curve data. Up to three curves may be exported
dependent on the Device Configuration: CurveFV_1, CurveFV_2, CurveFV_3. The numbers signify
1 = best test, 2 = second best test, 3 = third best test. The additional suffix p is, in turn, used
for Post tests.
•
CurveFV contains precisely the number CuFVLen of values. The same applies analogously to
CurveVT.
•
Scaling of the FV curve: the flow values in the table have a resolution of 10 ml/s (a value of 10
means a flow of 100 ml/s). The volume spacing between two points is 30 ml. The first measured
value at (0.0) is always omitted.
•
Scaling of the VT curve: The volume values in the table have a resolution of 10 ml (a value of
100 corresponds to 1000 ml). The time spacing between two measurement points is 60 ms. The
first point of the curve at (0.0) is always omitted.
•
Parameters signs: inspiration positive, expiration negative.
