14 Troubleshooting
Condition Solution
The Device (sensor) is not responding Disconnect and reconnect the sensor.
Check if the port settings in the settings menu
correspond with the used COM-port.
Measured values are incorrect Verify LOT number and perform a verification
test.
Check the flow transducer for potential
obstruction.
Do a volume calibration to check the
gain-factor and to recalibrate the device if
necessary.
Check to ensure that the patient's lips form a
tight seal around the flow transducer.
Use a nose clip on the patient.
Values are too high (intermittent) Retest with fingers positioned properly
around the flow transducer. Do not block the
end of the flow transducer with your fingers or
hand.
Check the flow transducer for obstruction
caused by patient saliva or phlegm. Replace
the flow transducer.
Check to ensure that the patient's airways
are not restricted by excessive bending.
Correct the patient's posture.
Flow data is out of range (measured
flow has exceeded the allowable limits) Recalibrate with a 3-liter syringe.
The program does not predict values or
the values appear incorrect Check in the settings menu to see if the
correct author is selected.
Verify that the date of birth, gender, race and
the height of the patient are correctly entered
in the patient card; these are needed for the
calculation of the predicted values. For some
prediction norms the patient’s weight is also
obligatory.
Unable to calibrate Verify sensor calibration information.
Check the connection between flow
transducer and sensor.
