9 Test Types

When you enter the patient data or select an existing patient, you will see the Test menu with the following selection options:

· FVC (expiration)

· FVL (inspiration and expiration)

· Tidal FVL

· MVV

· Slow VC

It is also possible to add a “Post” test to a FVC or FVL Test.

The various measurement methods are outlined below. Good co-operation on the part of the patient is essential with all methods. Consequently, you should explain to the patient clearly beforehand what he or she has to do and motivate the patient to co-operate. Choose the required measurement method with keys (>) or (<) and confirm with ENTER.

9.1

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

TM into the instrument. When doing this, please ensure that the arrow on the spirette

TM

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 cessary to block off the spirette

TM

TM

while it is setting the baseline. It is ne-

at one end in order to ensure that the baseline is set precisely.

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 TM 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.

· At the end of the maneuver, you will see a message on the screen indicating whether the maneuver was acceptable. At least three acceptable, reproducible maneuvers must be performed before you see message "Session complete". In Frontline mode, only two acceptable, reproducible maneuvers need to be performed.

9.2

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 remove the spirette TM from his or her mouth after exhaling, but to follow up with a deep, maximum inhalation. Three acceptable tests should be conducted with this test as well.

9.3

Tidal FVL

In this test mode the patient can do tidal breathing before the full FVL maneuver, as described in Chapter 9.2. When the maneuver is finished press enter to manually stop the trial. This test mode is mainly used with the EasyOne–line setup.

9.4

Slow VC

Slow spirometry serves to determine the vital capacity and the lung volumes (see Chapter 7). You can repeat the maneuver several times. The best test is saved. Proceed as follows:

· Insert a spirette TM

into the instrument. Ensure that the arrow on the spirette

TM

lines up with the arrow on the instrument.

· Press ENTER when the patient is ready. You will now hear the sensor buzz.
