WARNING
Correct positioning of the mouthpiece extending under the dental arch in the patient's mouth is fundamental so as to avoid
any turbulence which could erroneously affect the spirometry results.
WARNING
If possible it is recommended to stand up while performing the test. During expiration it is recommended to bend forward
the upper part of the body so as to release all the air out with the aid of the abdominal muscles.
By touching the
icon the user may access the spirometry testing area which includes the following tests:
FVC spirometry testing
VC type spirometry test
MVV type spirometry test
test with broncodilator
Once a test is selected the screen will display information concerning the type of turbine in use (reusable or disposable) including the
necessary information to complete the test in the correct manner.
WARNING
A test is saved with the name of the last patient displayed. If a test refers to a previously saved patient, then prior to performing
a test the user must recall that patient from the database as described in paragraph 2.9.2
To end a test press the power (ON/OFF) key placed on the top side of the device pressed
2.12.1
FVC test
Proper execution of a FVC test must take into account the phases as described on the screen, more specifically:
INSPIRE quickly
EXPIRE forcefully
INSPIRE forcefully
It is possible (and may be helpful) to start the test by breathing at rest for a few moments. When ready to start inspire slowly as much air as
possible (made easier by raising the arms wide apart) and then make a complete expiration as fast as possible. Then with the mouthpiece always
held firmly in the mouth, complete the cycle by inspiring again as quickly as possible. This final inspiration may be left out if the inspiratory
parameters (FIVC, FIV1, FIV1%, PIF) are not of interest.
The optional initial inspiration phase can also be performed before inserting the mouthpiece in the mouth.
After inspiring slowly and deeply, the following expiration must be made with the maximum effort by expiring all the air in the lungs as
fast as possible.
After 6 seconds of expiration the device will emit a continuous beep, this helps the user to understand whether the minimum expiry time
has been reached, as recommended by the main international respiratory institutions.
WARNING
Accurate spirometry testing requires that the patient expire all the air in the lungs.
The test may be carried out several times by repeating the cycle without taking the mouthpiece out of the mouth, in which case Spirodoc
recognises the best test (largest FVC+FEV1) and will automatically display the results of the best test.
To end the test touch the OK icon.
During the test the Spirodoc emits "beeps", the frequency of which are directly proportional to the inspired and expired velocity of the
air. This helps the doctor understand when the velocity of the air is approaching zero, and the patient has almost exhausted all of the
inspired or expired volume.
In the maintenance section an explanation is given as to how this feature can also function as a very simple checking system for the
correct operation of the mobile "rotor" of the turbine.
For the FVC test to be judged as acceptable, besides breathing as deep as possible, it is also required that the forced expiratory time (FET)
is sufficiently long to allow for the complete expiration of all air contained in the lungs.
