Fault: Oximetry – Input Signal
Unstable
Poor oximetry cable/catheter connection
Debris or film obstructing oximetry cable/
catheter connector lens
Oximetry cable malfunction
Catheter kinked or damaged
Verify secure oximetry cable /catheter connection
Clean oximetry cable /catheter connectors with 70%
isopropyl alcohol and swab, let air-dry and recalibrate
Change oximetry cable and recalibrate
Replace catheter if damage is suspected and recalibrate
Fault: Oximetry – Signal
Processing Malfunction
Oximetry cable malfunction Power monitor off and on to restore platform
Change oximetry cable and recalibrate
If problem persists, contact Edwards Technical Support
Fault: Oximetry Cable Memory Oximetry cable memory malfunction Disconnect and then reconnect the cable
Change oximetry cable and recalibrate
Fault: Oximetry Cable
Temperature
Oximetry cable malfunction Power monitor off and on to restore platform
Change oximetry cable and recalibrate
If the cable is wrapped in fabric or sitting on an insulating
surface such as a pillow, place it on a smooth surface that
allows it to readily dissipate heat
If the cable body feels warm, allow it to cool before
operating again
If problem persists, contact Edwards Technical Support
Fault: Oximetry Cable
Malfunction
Internal system malfunction Power monitor off and on to restore platform
If problem persists, contact Edwards Technical Support
Alert: Oximetry – SQI = 4 Low blood flow at catheter tip or catheter
tip against vessel wall
Significant change in HGB/Hct values
Catheter tip clotted
Catheter kinked or damaged
If the cable is wrapped in fabric or sitting on an insulating
surface such as a pillow, place it on a smooth surface that
allows it to readily dissipate heat
If the cable body feels warm, allow it to cool before
operating again
Verify proper catheter position (for SvO
2
, verify proper
catheter position in the pulmonary artery):
• Confirm wedge pressure balloon inflation volume of
1.25-1.50 ml (for SvO
2
only)
• Confirm appropriate catheter placement for patient's
height, weight, and insertion site
• Consider chest x-ray evaluation of proper placement
Aspirate then flush distal lumen per hospital protocol
Update HGB/Hct values using update function
Check catheter for kinking and recalibrate
Replace catheter if damage is suspected and recalibrate
