Type
First, the setting FVC, Ex. only or FVL, Ex./In. determines whether the
bronchial provocation test is performed using an FVC test or an FVL test.
Second, if you have integrated
EasyOne Connect with your EMR system and if
you use the GDT plug-in, the setting FVC, Ex. only or FVL, Ex./In. is also
relevant. With this setting, you can configure which test of the two is initiated
when the EMR system requests forced spirometry.
To allow the patient to breathe regularly through the
EasyOne Flow Tube
before the breathing maneuver, choose Tidal Breathing . This check box is
only available when Manual Test Stop is selected under Utilities
> Configuration > Test > General > Test Procedure .

End-of-maneuver criteria selection
If you choose the FVC option, the measurement continues until the end of test
criteria are met or until you end the test manually. With this setting, all the
intermediate flow values, e.g. MEF
25
, FEF
25-75
, are reported.
If you choose the FEV6 option, the measurement stops after six seconds. With
this setting, none of the intermediate flow values, e.g. MEF
25
, FEF
25-75
, are
reported.
The FVC test determines the forced expiratory vital capacity. The forced
expiratory vital capacity is the maximum volume that the patient can exhale
during the FVC breathing maneuver and is indicated by the FVC value in the
report.
The FEV
6
value indicates the forced expiratory volume that the patient has
exhaled after six seconds.
For diagnostic purposes, the FVC value is comparable with the FEV
6
value. The
advantage of choosing the FEV6 option is that the FVC test only takes the
fixed duration of six seconds and is less demanding for the patient (see
Ferguson (2000/NLHEP) [4]). The disadvantage is that the intermediate flow
values, e.g. MEF
25
, FEF
25-75
, cannot be reported.
