Forced Spirometry:
After clicking the Forced Spirometry icon on the main screen, a screen with a start button
and temperature reading is displayed. This temperature reading is the ambient room
temperature as measured by the unit. If the operator wishes to modify the temperature
value, he may do so by clicking on the displayed temperature, and he will then be given the
opportunity to enter a temperature to over-ride the automatic temperature. The ambient
temperature is used for BTPS correction during inspiration. The same is true when
conducting Relaxed Spirometry. The temperature can only be over-ridden before
performing the first blow in a test sequence.
Press
in the bottom right corner of the Spirometry Examination screen to initiate the
test.
Both flow-volume and volume-time graphs are shown and the unit will beep to indicate that it
is ready. At this point the operator can select a tab for a single graph or the Incentive tab, if
he wishes to view the FV graph, VT graph or Child Incentive graphic as an alternative to the
default Flow Volume loop and Volume Time graph during the live blow.
Instruct the patient to hold the mouthpiece between the teeth, and then apply the lips for an
airtight seal and breathe normally through the device. The patient should then be instructed
to breathe in rapidly until their lungs are completely full and the without delay, blast out the
air in their lungs as fast as they can and continue, until they cannot squeeze any more air out
of their lungs. They should aim to exhale until the graph border turns pink when a plateau in
the volume/time curve is detected, or to the point where they simply cannot squeeze any
more air out. They should then inhale as deeply and as rapidly as possible back to full lung
capacity, before removing the unit from their lips. After four seconds has passed without the
unit detecting any further flow, it will sound a beep and a test summary will be shown.
