Troubleshooting

Faults and Actions

This section describes system faults and provides resolutions to correct
these faults.

Questionable Pressure Accuracy

1. Disconnect the unit from the external tubing.

2. Verify that the pressure port is vented to atmosphere.

3. Turn the power on and verify that the zero pressure reading before

FLOW CAL is less than 4 cm H

2

O.

4. Press the

FLOW CAL

key and verify that the pressure reads zero.

5. Connect the unit in parallel to a pressure source with a high precision

reference gauge (better than 0.1% FSO accuracy).

6. Apply pressure and verify the unit’s accuracy. If it is still not within

specification, disengage the unit, consult the manufacturer, and DO
NOT CONTINUE TO USE THE MONITOR IN THE CLINICAL
SETTING.

Inability to Set Pressure Low Limit Screen to Desired Value

Check the High Limit Screen setting and verify that it is greater than the
desired Low Limit set value by at least 6 cm H

2

O. If the difference equals

or exceeds this value, consult the manufacturer and DO NOT CONTINUE
TO USE THE MONITOR IN THE CLINICAL SETTING.

O

2

Sensor Failure

Check the sensor’s electrical connection and repeat the calibration process.
If the problem persists, change the oxygen sensor and recalibrate. If the
problem remains, consult the manufacturer and DO NOT CONTINUE TO
USE THE MONITOR IN THE CLINICAL SETTING.

Flow and Tidal Volume Measurement Error

Visually inspect the flow sensor tube and monitor to ensure that all
pressure connections are intact. Recalibrate the monitor. If the problem
persists, measure the exhaled volumes using a secondary source (i.e., a
hand-held spirometer). If the measurement of the monitor is not within
14% of the volume of the spirometer, remove the monitor from clinical use
for evaluation by a qualified service technician. If the problem persists
under bench conditions, consult the manufacturer and DO NOT
CONTINUE TO USE THE MONITOR IN THE CLINICAL SETTING.
