HemoSphere Advanced Monitor 13 Troubleshooting
13.6.6 PAP Faults/Alert
*NOTE This fault occurs while monitoring pulmonary artery pressure (PAP) with the pressure
cable in HemoSphere Swan-Ganz module monitoring mode.
13.6.7 General Troubleshooting
Alert: MAP – Pressure
Waveform Not Stable
Arterial waveform is inadequate to
measure blood pressure accurately
Integrity of pressure monitoring line is
compromised
Systolic pressure too high or diastolic
pressure too low
Fluid line is being flushed
Assess Edwards pressure monitoring system starting
from patient leading to pressure bag
Check the arterial waveform for severe hypotension,
severe hypertension, and motion artifact
Make sure the arterial catheter is not kinked or clotted
Make sure all arterial pressure lines are patent and
stopcocks are properly positioned
Make sure Edwards pressure sensor/transducer is
aligned with the patient’s phlebostatic axis
Zero the Edwards pressure sensor/transducer on
HemoSphere advanced monitor and confirm pressure
cable connection
Make sure the pressure bag is inflated and flush bag is at
least ¼ full
Perform Square Wave Test to assess the Edwards
pressure monitoring system frequency response
Table 13-18 HemoSphere pressure cable/Swan-Ganz module PAP faults/alerts*
Message Possible causes Suggested actions
Fault: PAP – Pressure
Disconnected
Pulmonary artery pressure low and non-
pulsatile
Pulmonary artery catheter disconnected
Cable connections not detected
Edwards pressure cable or sensor
malfunction
Internal system malfunction
Verify pulmonary artery catheter connection
Verify connection between pressure cable and sensor and
check for missing pins
Change pressure cable
Change pressure sensor
If problem persists, contact Edwards Technical Support
Table 13-19 HemoSphere pressure cable general troubleshooting
Message Possible causes Suggested actions
Connect pressure cable for CO
or pressure monitoring
Connection between the HemoSphere
advanced monitor and pressure cable has
not been detected
Verify connection between pressure cable and monitor
Disconnect pressure cable and check for bent/missing
pins
Change pressure cable
Connect CO pressure sensor
for CO monitoring
A CO-dependent key parameter is
configured
Connection between the pressure cable
and CO pressure sensor has not been
detected
The incorrect pressure sensor type is
connected
Verify connection between pressure cable and catheter
Verify that the pressure sensor connected is for CO
monitoring
Disconnect pressure cable and check for missing pins
Change Edwards CO sensor
Change pressure cable
