The slow vital capacity test can be started by carrying out several breaths at tidal volume. After three or four such breaths an acoustic
signal will be emitted to confirm that the ventilatory profile has been measured and that the patient may immediately proceed to perform
the VC or IVC test.
Expiratory Slow Vital Capacity: VC
After the acoustic signal inspire slowly as much as air as possible and expire slowly as much air as possible.
Inspiratory Slow Vital Capacity: IVC
After the acoustic signal exspire slowly as much as air as possible and inspire slowly as much air as possible.
To end the test touch the OK icon.
Follow the indications on the display carefully in order to carry out the test properly.
WARNING
To perform a test in the service menu with the item "PARAMETER setting", at least one parameter related to this test must
be activated/chosen, otherwise the icon will be disabled.
2.12.3 MVV Test
Start the test by carrying out a series of forced inspirations and expirations with the maximum possible amplitude. The suggested
frequency is 30 breaths per minute. The test will end automatically after 12 seconds.
WARNING
To perform a test in the service menu with the item "Set parameter", at least one parameter related to this test must be
activated/chosen, otherwise the icon will be disabled.
WARNING
The disposable mouthpiece and the disposable turbine must be replaced after a single patient test session.
2.12.4 POST test, after drug administration
WARNING
To carry out a POST test it is necessary to have carried out at least one PRE FVC test the same day; it is not possible to do
a POST test on the PRE VC or MVV tests; it is however possible to do a POST VC or MVV test if the database already
contains at least one PRE test carried out on the same day.
To carry out a POST test please access to the spirometry area touching the
icon.
A POST test is a spirometry test following the administration of a drug of some kind, usually a bronchodilator. The sign POST is shown
on the screen of the device (top right) during the following tests. On the RHS of the screen there is the icon
see all of the results from the PRE test as well as the relevant predicted values. The following tests made by the patient show the
following parameters:
•
Those values related to the test performed
•
Those values related to the best PRE test performed by the same patient the same day.(that is in the same test session)
•
The percentage variation between the PRE and POST values (in the CHG column)
It is not possible to perform a POST test with a patient whose PRE testing was not carried out on the same day.
If during a POST session a new patient is inserted or another is recalled from the archive the device will automatically exit the current
POST session.
2.13 Viewing the spirometric results
Following a FVC test, the spirometry test results are shown. The first screen displays:
- the Forced Vital Capacity Flow/Volume graph.
- the main parameters FVC, FEV1, FEV1%, PEF best acceptable in the session
- the percentage ratio compared to theoretical values
By scrolling on the right hand side of the screen it is possible to view all the parameters next to the chosen predicted values.
2.13.1 Spirometry test interpretation
Spirometry test interpretation is based on the Forced Vital Capacity (FVC) test. The test interpretation is indicated with one the following
