User manual
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.
2.11.3 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.
2.11.4 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 on the main screen and subsequently 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 which enables you to 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.
2.12 Viewing the spirometric results
Following a FVC test, the spirometry test results are shown. The first screen displays:

A Flow/Volume graph of the Forced Vital Capacity

All the parameters selected (with the percentage change compared to the predicted values) in a configuration menu.
By scrolling on the right hand side of the screen it is possible to view all the parameters next to the chosen predicted values.
2.12.1 Spirometry test interpretation
Spirometry test interpretation is based on the Forced Vital Capacity (FVC) test. The test interpretation is indicated with one the following messages:

Normal Spirometry

Mild obstruction

Moderate obstruction

Moder severe obstruct.

Severe obstruction

Very severe obstruction

Mild Restriction

Moderate Restriction

Moder Severe Restriction

Severe Restriction

Very severe Restriction

Obstruct. + Restrict
For a
POST test the messages are the same but instead of dealing with an “obstruction” the POST test refers to a “restriction”.
Through the use of a mathematical analysis applied to certain indices and parameters calculated in the FVC test , the
SPIRODOC is capable of
producing a list of quality control comments useful to assess the quality and reproducibility of the manouvers performed.
The quality control check assigns a letter for the current spirometry session as described below:
