4 Patient Alarms and INOPs
92
CO2 INOPs
<Press Label> Deactivated
INOP tone
A Pressure measurement label in the measurement device or extension has been deactivated, either by
connecting a Temp transducer in the shared Press/Temp socket, or by deactivating the label in the
Measurement Selection window.
The measurement automatically disappears from the display.
To switch the measurement on again, either reconnect a Pressure transducer or reactivate the
measurement label in the Measurement Selection window.
<Press Label> Equip Malf
Numeric is replaced by -?-
INOP tone
Contact your service personnel.
The pressure hardware is faulty.
<Press Label> No Pulse
Pulse numeric is replaced by -?-
INOP tone
This INOP can only arise when a pressure is selected as the pulse source. It occurs when the pulse rate
being measured is less than 25 beats per minute or the amplitude is less than three mmHg.
Check the catheter and connections to the patient.
<Press Label> No
Transducer
Numeric is replaced by -?-
INOP tone
Make sure that the pressure transducer is connected to the measurement device or module.
If you silence this INOP, the measurement will be switched off.
<Press Label> Noisy
Signal
Pulse numeric is replaced by -?-
INOP tone
This INOP can only arise when a pressure is selected as the pulse source. It occurs when the pulse
detector finds a pulse rate above 350 bpm. This is usually caused by movement artifact or electrical
interference.
<Press Label> Overrange
Numeric is replaced by -?-
INOP tone
Make sure that the measurement has been properly prepared and zeroed, and that the transducer is
level with the heart. If this INOP persists, try another transducer.
Possible causes are a measured pressure outside the allowed pressure range, or a broken wire to the
transducer.
<Press Label> Reduce
Size
Increase the scale for the pressure wave.
<Press Label> Unplugged
INOP tone
A Pressure measurement label has been deactivated, either by unplugging a module, or by deactivating
the label in the Measurement Selection window.
The measurement automatically disappears from the display.
To switch the measurement on again, either replug the module or reactivate the measurement label in
the Measurement Selection window.
<Press Label>
Zero+Check Cal
Numeric is replaced by -?-
Perform a zero and check the calibration of the transducer.

INOP Message, Indication What to do
INOP Message, Indication What to do
CO₂ Auto Zero
Numeric is replaced by -?-
if the Autozero lasts >15 sec,
INOP tone sounds.
The automatic zero calibration is in progress. This typically takes 10 seconds. During this time the CO
2
values may not be updated, or they may be replaced by -?-. Wait until the zero calibration is complete
to resume monitoring.
CO₂ Cal Failed
Numeric is replaced by -?-
INOP tone
Make sure that the Cal cell was changed between CAL1 and CAL2. Repeat the calibration. If the
INOP reappears, try another transducer. If the INOP persists, contact your service personnel.
