Invasive Blood Pressure (IBP1, IBP2)
Displayed Message Possible Cause Suggested Action
IBP Low Pulse Systolic and diastolic val-
ues are less than 60% of
the baseline.
Elevated heart rate.
Hemodynamic interfer-
ence (e.g., decreased
stroke volume).
Clot has formed on the
catheter tip.
Catheter is lodged
against the vessel wall.
Transducer is not prop-
erly aligned to the
patient’s heart level.
Air in tubing.
Kinked tubing.
• Check the patient.
• Zero and check the trans-
ducer calibration factor.
• Remove the clot by open-
ing the stopcock to the
patient and drawing back
with a sterile syringe.
• If you cannot draw back,
follow your hospital pro-
cedure for removing clots.
• Straighten all tubing. If air
is present in the tubing,
follow your hospital pro-
cedures for removing,
flushing and reposition-
ing the catheter.
Message: IBP Static
Parameter value:
<value>
This message appears
when the invasive pres-
sure alarms are on while
zeroing.
No pulse.
• Turn combined systolic
and diastolic alarm off.
• Check the patient.
• Repeat zeroing.

Message: IBP Dia >UL
<value>
Parameter value:
<value>
The patient’s invasive
pressure falls outside the
current alarm limits.
The current alarm limits
are inappropriate for this
patient.
• Observe the patient.
• Change the current alarm
limits.
Message: IBP Too High
Parameter value: +++
Message: IBP Too Low
Parameter value: - - -
The value is outside the
measurement range.
The transducer may be
picking up pressure from
the IV infusion system.
• Check the connections
and cables.
• Zero and calibrate the
transducer, if necessary.
Note that the label “IBP” is replaced on screen with the user-defined label (e.g.,
“ART Too Low”).
