WARNING
The disposable mouthpiece and the disposable turbine must be replaced after a single patient test session.
2.9.4
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 pressing
and subsequently pressing
.
A POST test is a spirometry test following the administration of a drug of some kind, usually a bronchodilator. The sign
“
POST
Phase”
is shown on the screen of the device (center) on the first screen of the spirometry area.. 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.

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
pressing
it is be possible visualize the best value of FVC, FEV1, FEV1%
and PEF with the percentage change compared to the predicted values.
By scrolling with
and
it is possible to view all the parameters next to the chosen predicted values.
2.10.1
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
obstruction/restriction mild
obstruction/restriction moderate
obstruction/restriction moderate severe
obstruction/restriction severe
obstruction/restriction very severe
A last level of interpretation is “
restobstruction
”; the indication on the
traffic lights will be the worst case between restriction
and obstruction.
Through the use of a mathematical analysis applied to certain indices and parameters calculated in the FVC test , the
Spirobank II
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:
PRE test
A = At least to acceptable manouvers, with the highest two FEV1 values matching to within 100 mL and the largest two FEV6 values
within 100 mL
B= At least two acceptable manoeuvres, with the FEV1 values matching to within 101 to 150 mL
C= At least two acceptable manoeuvres, with FEV1 values matching to within 151 to 200 mL
D= only one acceptable manoeuvres, or more than one, but the FEV1 values not matching to within 200 mL (with no interpretation).
F= No acceptable manoeuvres (with no interpretation).
