All subject data must be entered before carrying out a spirometry test.
The test can be made from the main screen or from any display that shows a previous test result (last test, best test or test in memory).
Select the spirometry test:
To make the FVC test tests
To make the VC/IVC and ventilatory profile
To make the MVV test.
WARNING
With standard NAHNES III it is not possible to make VC or MVV tests
When a test is being performed the display will show the real time Flow/Volume curve or the Volume/time curve (if the pediatric incentive is set, then the volume/time curve is displayed.).
The test must begin within 30 seconds of pressing the start key, otherwise the test is interrupted and the device returns to the main screen.
2.6.1 Spirometry testing
Insert a new mouthpiece into the MiniFlowMeter mouthpiece holder.
Fit the nose clip onto the nose of the subject, to ensure that air cannot escape through the nostrils.
The subject must insert the mouthpiece well into the mouth, it should be inserted at least 2 cm beyond the front teeth and held between the teeth, closing the lips to ensure that air cannot escape from the sides of the mouth.
Breathe as directed according to the test to be undertaken, details follow.
Make the test in either a standing or a sitting position. During total expiration (slowly or forced) lean forward to help the expiratory action with a compression of the abdomen.
FVC
If required (this part is optional), before the test make several breaths at rest. When ready, inspire slowly as much air as possible (opening the arms helps) and then expire all of the air as fast as possible. Then, without removing the mouthpiece from the mouth, finish the test by inspiring again as fast and as completely as possible.
This final inspiration is not necessary in the case that the inspiratory parameters (FIVC,
FIV1, FIV1%, PIF) are not required.
The cycle can be repeated several times, without removing the mouthpiece, in which case
Spirolab
III will automatically select and show the best test and measured parameters. To end test press or just wait for 10 seconds after the last volume cycle, the test terminates automatically.
