13.5.3 iCO Faults/Alerts
Table 13-9 HemoSphere Swan-Ganz module iCO faults/alerts
Message Possible causes Suggested actions
Fault: iCO – Check Injectate
Probe Connection
Injectate temperature probe not detected
Injectate temperature probe malfunction
Patient CCO cable malfunction
Verify connection between patient CCO cable and
injectate temperature probe
Change injectate temperature probe
Change patient CCO cable
Fault: iCO – Check Thermistor
Connection
Catheter thermistor connection not
detected
Monitored blood temperature is <15 °C or
>45 °C
Patient CCO cable malfunction
Verify that catheter thermistor is connected securely to
patient CCO cable
Verify that blood temperature is between 15 – 45 °C
Disconnect thermistor connection and check for bent/
missing pins
Change patient CCO cable
Fault: iCO – Injectate Volume
Not Valid
In-line probe injectate volume must be 5
mL or 10 mL
Change injectate volume to 5 mL or 10 mL
Use a bath type probe for an injectate volume of 3 mL
Fault: iCO – Injectate
Temperature Out of Range,
Check Probe
Injectate temperature < 0 °C, > 30 °C or >
BT
Injectate temperature probe malfunction
Patient CCO cable malfunction
Verify injectate fluid temperature
Check injectate probe connections for bent/missing pins
Change injectate temperature probe
Change patient CCO cable
Fault: iCO – Blood Temperature
Out of Range
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 bolus injections when blood temperature is
within range
Alert: iCO – Unstable Baseline Large pulmonary artery blood temperature
variations detected
Allow more time for blood temperature baseline to
stabilize
Use Manual mode
Alert: iCO – Curve Not Detected No bolus injection detected for >4 minutes
(Automatic mode) or 30 seconds (Manual
mode)
Restart Bolus CO monitoring and proceed with injections
Alert: iCO – Extended Curve Thermodilution curve slow to return to
baseline
Injectate port in introducer sheath
Possible cardiac shunt
Verify correct injection technique
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
Ensure injectate port location is outside of the introducer
sheath
Use “iced” injectate and/or 10 mL injectate volume to
create a large thermal signal
Alert: iCO – Irregular Curve Thermodilution curve has multiple peaks Verify correct injection technique
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
Use “iced” injectate and/or 10 mL injectate volume to
create a large thermal signal
