Meaning and Corrective Action
Meaning and Corrective Action
Calibration function
is unavailable
BPM
The system will not initiate calibration if BPM(s) are
not detected.
Ensure proper placement of the BPM(s) in the
Calibrator. The BPM is seated properly if it can
resist a gentle tug. Ensure the BPM(s) are properly
connected to the Core. If the issue persists, contact
Terumo Cardiovascular Technical Support.
No gas fl ow
(Left or Right)
G405
G406
The calibration gas is not fl owing freely through
the sensor during calibration. The left or right
designation indicates which calibration pocket
is affected. This can be caused by closed venting
caps, blocked gas ports or blocked fi lter/sparger
assemblies.
Ensure the large blue venting cap(s) on the top of
the Shunt Sensor(s) are loosened and that the blue
Luer cap(s) on the fi lter(s) are removed. Ensure the
BPM(s) are securely seated in the Calibrator. Retry
calibration. If still no gas fl ow is detected, replace
the Shunt Sensor(s) and try again.
If the problem persists after several retries, contact
Terumo Cardiovascular Technical Support.
No (Arterial or Venous)
Flow Detected
G436
G437
The Arterial or Venous Shunt Sensor is not
responding to gas fl ow during calibration. This can
be caused by closed venting caps or compromised
sensors.
Ensure the large blue venting cap(s) on the top
of the Shunt Sensor(s) are loosened. If the proper
setup was confi rmed, this indicates the problem
is with the Shunt Sensor(s). Replace the Shunt
Sensor(s) and try again. If the problem persists,
contact Terumo Cardiovascular Technical Support.
