WARNING
If a new dose is set after a POST test then the device creates a new test session, still POST. A new test code ID is allocated.
The interpretation is not based on the previous sessions with different drug doses; only the new test is utilized for the interpretation.

ISUALISATION OF SPIROMETRY DATA
The image below describes the information which appears inside the spirometry test results screen.
In particular, in this screen it is possible to visualise the data relative to a single curve by pressing respectively key 1, 2 or 3 starting from the best test onwards.
WARNING
For standard NAHNES III the parameters shown are:
FEV6, FEV1, FEV1/FEV6%, FEF2575, FVC, FEV1/FVC
By visualising the single curve it is then possible to directly carry out a new spirometry PRE or POST test or oximetry test
On the current patient by pressing respectively one of the following keys , , , , . You can also do this if you recall a best test by selecting key or the last test by selecting key test selected will be carried out on the current patient.
(for spirometry) or key (for oximetry); the
WARNING
If the last spirometry test carried out was a POST test, the POST session should be maintained until a new patient is recalled from the archivi or a new patient created.

EST QUALITY CONTROL
-
SPIROMETRY
Through a mathematical analysis (quality control) which is applied to certain calculated indices and parameters, the spirolab III produces a series of comments, helpful for understanding the reliability of the test made.
This control quality check assigns a letter for the current session as described below:
PRE Test
A = At least two acceptable manoeuvres, 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).
POST Test
A = two acceptable (1) FEV1 values matching within 100 mL
B= two acceptable (1) FEV1 values matching within 200 mL
C= two acceptable (1) FEV1 values that do not match within 200 mL
D= only one acceptable (1) FEV1 manoeuvre
F= No acceptable (1) FEV1 manoeuvres
Acceptable manoeuvre means: good start and satisfactory exhalation (duration and flow)
Where several comments related to the single test are calculated, spirolab III will only show the most important to facilitate the test spirolab III
