13.5.1 CO Faults/Alerts
Table 13-7 HemoSphere Swan-Ganz module CO faults/alerts
Message Possible causes Suggested actions
Fault: CO – Blood Temp Out of
Range (<31 °C or >41 °C)
Monitored blood temperature is <31 °C or
>41 °C
Verify proper catheter position in the pulmonary artery:
• confirm wedge pressure balloon inflation volume of
1.25 - 1.50 mL
• confirm appropriate catheter placement for patient’s
height, weight, and insertion site
• consider chest x-ray for evaluation of proper place-
ment
Resume CO monitoring when blood temperature is within
range
Fault: CO – Cardiac Output <
1.0 L/min
Measured CO < 1.0 L/min Follow hospital protocol to increase CO
Resume CO monitoring
Fault: CO – Catheter Memory,
Use Bolus Mode
Poor catheter thermal filament connection
Patient CCO cable malfunction
Catheter CO error
Patient CCO cable is connected to cable
test ports
Verify secure thermal filament connection.
Check catheter/ patient CCO cable thermal filament
connections for bent/missing pins
Perform patient CCO cable test
Change patient CCO cable
Use Bolus CO mode
Replace catheter for CO measurement
Fault: CO – Catheter
Verification, Use Bolus Mode
Patient CCO cable malfunction
Catheter CO error
Catheter connected is not an Edwards
CCO catheter
Perform patient CCO cable test
Change patient CCO cable
Use Bolus CO mode
Verify catheter is an Edwards CCO catheter
Fault: CO – Check Catheter and
Cable Connections
Catheter thermal filament and thermistor
connections not detected
Patient CCO cable malfunction
Verify patient CCO cable and catheter connections
Disconnect thermistor and thermal filament connections
and check for bent/missing pins
Perform patient CCO cable test
Change patient CCO cable
Fault: CO – Check Thermal
Filament Connection
Catheter thermal filament connection not
detected
Patient CCO cable malfunction
Catheter connected is not an Edwards
CCO catheter
Verify that catheter thermal filament is connected securely
to patient CCO cable
Disconnect thermal filament connection and check for
bent/missing pins
Perform patient CCO cable test
Change patient CCO cable
Verify catheter is an Edwards CCO catheter
Use Bolus CO mode
Fault: CO – Check Thermal
Filament Position
Flow around thermal filament may be
reduced
Thermal filament may be against vessel
wall
Catheter not in patient
Flush catheter lumens
Verify proper catheter positions in the pulmonary artery:
• confirm wedge pressure balloon inflation volume of
1.25 - 1.50 mL
• confirm appropriate catheter placement for patient’s
height, weight, and insertion site
• consider chest x-ray for evaluation of proper place-
ment
Resume CO monitoring
