6.1 Test type 'FVC (Expiration)'

This is the most commonly used spirometric measurement. Prepare the patient as described in Chapter
5.1. before you start the test. Then proceed as follows.
•
Insert a spirette™ into the instrument. When doing this, please ensure that the arrow on the
spirette™ is lined up with the arrow on the instrument.
•
Press ENTER when the patient is ready. You will now hear the sensor buzz.
•
The instrument prompts you to avoid flow in the spirette™ while it is setting the baseline. It is
necessary to block off the spirette™ at one end in order to ensure that the baseline is set pre-
cisely. An audible signal sounds when the baseline is set. You will see the prompt "Blast out..."
on the screen.
•
Hand the instrument to the patient and ask the patient to breath in deeply first, then to insert
the spirette™ correctly into his or her mouth, to exhale as firmly and quickly as possible and to
continue exhaling until all the air has been exhaled.
•
A message indicating whether the spirometry maneuver was acceptable is displayed at the end
of the spirometry maneuver. At least three acceptable, reproducible spirometry maneuvers
must be performed until message "Session Complete! Great Job!" is displayed. Only two ac-
ceptable, reproducible spirometry maneuvers need be conducted in Frontline mode.

6.2 Test type 'FVL (Inspiration and Expiration)'

With this test mode, a deep inhalation follows the exhalation maneuver directly. Proceed in
the same way as with the above-described FVC test. However, instruct the patient not to re-
move the spirette™ from his or her mouth after exhaling, but to follow up with a deep, maxi-
mum inhalation. Three acceptable tests should be conducted with this test as well.

6.3 Test type 'Slow VC'

Slow spirometry serves to determine the vital capacity and the lung volumes (see Chapter 6.8).
You can repeat the maneuver several times. The best test is saved. Proceed as follows:
•
Insert a spirette™ into the instrument. Ensure that the arrow on the spirette™ lines up with the
arrow on the instrument.
•
Press ENTER when the patient is ready. You will now hear the sensor buzz.
•
The instrument now prompts you to avoid flow in the spirette™ while it is setting the baseline.
It is advisable to block off the spirette™ at one end to ensure the baseline is set precisely. An
audible signal sounds when the zero point is set.
•
The patient must now insert the spirette™ into his or her mouth and breathe at rest (about 3-5
breaths) until you hear an audible signal.
•
The patient must then take a deep inspiration followed by a maximum exhalation.
•
The instrument stops automatically at the end of the maneuver.
If you are only interested in the vital capacity without determination of the other volumes the VC ma-
neuver can also be performed without waiting for the acoustic signal.
At the end of the SVC test you can decide to immediately add an FVC test. If you do so the parameter
FEV1/VC (Tiffeneau) is also shown on the printed report of the FVC test.
