Condition Causes Actions
When printing, text prints correctly but
FVC curve does not. Print settings Make sure that the desired curve is selected. See “To
Print a Test” on page 47.
Unable to calibrate. • Poor connection between flow
transducer and sensor.
• Damage to flow transducer.
• Leak during calibration.
• Uneven calibration strokes.
• Check the connection between flow transducer
and sensor.
• Replace the flow transducer if it is damaged.
• Ensure that the connection between the
calibration syringe and flow transducer is tight
with no leaks.
• Use even strokes in calibration.
No sensor detected. Poor connection between the sensor and
the electrocardiograph. Disconnect and reconnect the sensor.
Does not print. • Out of paper.
• Paper jam.
• Load paper. See the electrocardiograph manual.
• If paper is jammed, clear it, then reload.
Values are too high (intermittent). • Patient’s fingers obstructed the screen
on the back of the flow transducer,
causing high back pressure and false
reading.
• Patient’s lips were not tightly sealed
around the flow transducer.
• Spirometer was calibrated with the
wrong size syringe.
• Retest.
• Recalibrate with a 3-liter syringe. See
“Calibrating the Spirometer” on page 21.
Values are too high (consistently). Pressure connection is partially obstructed. Remove any foreign substance from the flow
transducer or pressure tubing.
Predictive values are blank. • The selected norm does not support
certain values, and composite norm
values are disabled. • Re-enter age/birthdate, height, gender, race.
See
Step b on page 40.
• Enable composite norm values. See “Reviewing
the Operation Settings” on page 13.
The flow sensor has been dropped. Accident. Recalibrate. See “Calibrating the Spirometer” on
page 21.
Report does not print parameters or
graphs. Improper print settings. Check print settings. See “Reviewing the Spirometry
Print Settings” on page 17.
Patient test values differ from values
expected by physician. Various. • If the transducer is contaminated with sputum or
secretions, replace it.
• Verify that proper barometric pressure has been
entered. See
“Calibrating the Spirometer” on
page 21.
• Verify the patient data.
• Eliminate any leaks in the pressure tubing.
• Retest using a nose clip.
• Replace the sensor if damaged.
• Recalibrate.
• Replace the transducer and retest.
