case: subject file
To perform a POST test on a patient already in memory, firstly “recall from memory” the relavant PRE test spirometry
parameters from the same subject file.
Press ; select FILE NO. from the PRE test. Confirm with .
Press to activate the POST phase.
When the POST phase is activated, the patient data are shown and “POST” appears on the upper left part of the
screen.

In the POST phase, having selected one of these three tests or , the administered drug dose must
be entered.
Whenever the test is repeated using the same dose, the best test related to the dose used is saved.
When the dose is changed, then a new record is made with a progressive FILE number. For example, if three tests are
made on a subject at different doses, then three different records (POST tests) are saved for that subject.
Afterwards the separate best POST tests can be viewed.
The subject code in the POST test is the same as for the related PRE test.
In the POST phase, the measured result is compared to the values of the related PRE test.
The Flow/Volume curves of the PRE test and related POST test are shown superimposed.
After the two curves, the measured parameters (POST), the related PRE values and the percentage variations between
POST and PRE are also shown.

Physiological test (placebo)
It is common practise prior to a POST test to carry out a test using physiological solution in place of a drug, to examine
the subject’s response to such a stimulus.
If the subject is healthy then the reaction to a placebo is almost zero, but in the case of hypersensitivity even this
stimulus can have some effect.
In the physiological test the amount of the dose to enter is zero and it is still possible to compare the POST results with
those of the PRE test.
The POST phase will show a coloured string highlighting the words POST FILE No. and DOSE.
The POST test can be activated both from the subject file on the main screen and also from the test results (
or ). This makes passing to the POST test phase more simple.
When viewing a subject file, only the following keys can be used:
• keys;
• ID# key (to make a new spirometry test with the current subject’s data file);
• key (to make a POST test);
• (to print selected test);
• and display keys;
• key to go back to the Data Management Menu;
• (exit key);
• No. 1, 2, 3 keys (in the event that one or more tests have been carried out).
2.7 TEST QUALITY CONTROL - SPIROMETRY
Through a mathematical analysis (quality control) which is applied to certain calculated indices and parameters, the
SpirolabIII produces a series of comments, helpful for understanding the reliability of the test made.
ERROR IN Vext and PEFT
If the extrapolated volume Vext is greater than 500 mL or more than 5% of the FVC, or if the PEFT (time to peak flow) is
greater than 200 ms, this message is shown:
