PPV BAD SIGNAL
at Information Center
PPV The arterial pressure source selected for PPV is not providing a
pulsatile signal.
PPV CHK SOURCES PPV The arterial pressure source selected for PPV is unplugged or
switched off. When this INOP has displayed for 1 minute PPV
will be switched off.
<Pressure label> ARTIFACT
Numeric questionable
PRESS A non-physiological event is detected (for example, a flush or
blood sample). A resulting high limit alarm will be suppressed.
<Pressure label>
DEACTIVATED
INOP tone
PRESS A Pressure measurement label in the measurement device or
extension has been deactivated, either by connecting a Temp
transducer in the shared Press/Te m p s o ck e t , o r b y de a c ti v a ti n g
the label in the Measurement Selection window.
The measurement automatically disappears from the display.

Pressure transducer or reactivate the measurement label in the
Measurement Selection window.
<Pressure label> EQUIP
MALF
Numeric is replaced by -?-
INOP tone.
PRESS Contact your service personnel.
The pressure hardware is faulty.
<Pressure label> NO
TRANSDUCER
Numeric is replaced by -?-
INOP tone.
PRESS 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.
<Pressure label> NOISY
SIGNAL
Pulse numeric is replaced by -?-
INOP tone.
PRESS 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 350bpm. This is usually caused by movement
artifact or electrical interference.
<Pressure label> NON-
PULSATILE
Pulse numeric is replaced by -?-
INOP tone.
PRESS 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.
<Pressure label>
OVERRANGE
Numeric is replaced by -?-
INOP tone.
PRESS 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.
<Pressure label> REDUCE
SIZE
PRESS Increase the scale for the pressure wave.
<Pressure label>
UNPLUGGED
INOP tone.
PRESS 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 s w i tc h th e m e a su r em e n t o n a g ain, either replug the module
or reactivate the measurement label in the Measurement
Selection window.
<Pressure label>
ZERO+CHECK CAL
Numeric is replaced by -?-
PRESS Perform a zero and check the calibration of the transducer.
