3 Patient Alarms and INOPs
87
Spirometry INOPs
BIS SENSOR DISCONN
INOP tone
The sensor is not properly connected to the patient interface cable (PIC) and/or the PIC is not
properly connected to the DSC or BISx, or the sensor or PIC or DSC or BISx may be faulty.
Check all the connections.
Disconnect and reconnect the sensor, PIC, DSC, BISx.
If the INOP persists, replace the sensor.
If the INOP persists, replace PIC. If INOP persists, contact your service personnel.
Silencing this INOP switches the measurement off.
BIS SENSOR INCOMPT
INOP tone
Unsupported sensor connected or sensor type unknown or not supported by your software revision.
Replace the sensor, using only Philips supported sensors.
BIS SENSOR MALFUNC
INOP tone
Malfunction in the sensor hardware, most often caused by liquids permeating into the connectors OR
patient interface cable (PIC) or DSC or BISx may be faulty.
Replace the sensor. Manually initiate a Cyclic Impedance Check. Make sure all electrodes pass the test.
Make sure that the both sides of the PIC connector (between PIC and sensor) are dry. If you are not
sure that the connector is dry, replace the PIC until it has dried. If this INOP persists, contact your
service personnel.
BIS SENSOR USAGE
INOP tone
Excessive sensor usage. Replace sensor.
A Cyclic Impedance Check will start automatically.
BIS SQI < 15% (INOP tone)
OR
BIS SQI < 50% (no INOP
tone)
If the signal quality is below 50%, BIS numerics cannot be reliably derived.
If the signal quality is below 15%, no BIS numerics can be derived.
This may occur as a result of artifacts such as those generated from motion or the presence of
electrocautery devices. Make sure the sensor is properly attached to the patient. Manually initiate a
Cyclic Impedance Check. Make sure all electrodes pass the test. Make sure the patient is completely
relaxed (even small motions of the facial muscles affect the signal quality).
BIS UNPLUGGED
INOP tone
Plug in the BIS module. Silencing this INOP switches off the measurement.
BISx DISCONNECTED
INOP tone
The BISx is not connected to the BIS module or the BIS interface board. Silencing this INOP switches
the measurement off.
BISx INCOMPATIBLE
INOP tone
The BISx software is not compatible with the BIS module or with the MP20/MP30 monitor software.
A software upgrade may be required. Contact your service personnel.
BISx MALFUNCTION
INOP tone
The BISx is faulty. Disconnect and reconnect it to the module or BIS interface board. If the INOP
persists, replace the BISx.
MP20/MP30 - Malfunction on interface board. If the INOP persists, contact your service personnel.
INOP Message, Indication What to do
INOP Message, Indication What to do
AWFCHANGE SCALE Airway flow signal exceeds range of selected scale. Adjust scale to display complete wave.
AWPCHANGE SCALE Airway pressure signal exceeds range of selected scale. Adjust scale to display complete wave.
AWVCHANGE SCALE Airway volume signal exceeds range of selected scale. Adjust scale to display complete wave.
SPIRO ALARMS SUPPR Alarming is suppressed for the spirometry module.
SPIRO CANNOT MEAS Measurement is at its limit, e.g. ambient pressure out of range.
SPIRO GAS COMPENS? Gas compensation is set to Gas Analyzer but not all gases necessary for compensation are
measured by a gas monitor. Some of the fall-back values provided by the user are used. Measurement
accuracy might be reduced.
SPIRO INCOMPATIBLE Module revision not compatible with the host monitor software revision. Contact your service
personnel.
SPIRO MALFUNCTION Module failure detected. Contact your service personnel.
