Alert: Unable to Switch to Finger
Cuff #2
Error detected in Finger Cuff #2.
Error detected in Pressure Controller.
Allow System to automatically resolve issue.
Check Finger Cuff and Pressure Controller air tubes.
Check Pressure Controller - Pump-Unit connection.
Replace Cuff.
Replace Pressure Controller.
Fault: Finger Cuff #1 - BP
Measurement Error
Blood pressure measurement failed due to
movement or poor measurement
conditions.
Apply Finger Cuff to a different finger.
Resize Finger Cuff and replace Finger Cuff with different
size.
Restart measurement.
Fault: Finger Cuff #2 - BP
Measurement Error
Blood pressure measurement failed due to
movement or poor measurement
conditions.
Apply Finger Cuff to a different finger.
Resize Finger Cuff and replace Finger Cuff with different
size.
Restart measurement.
Fault: Check Blood Pressure
Waveform
Arterial waveform is inadequate to
measure CO accurately.
Poor pressure waveform over extended
period of time.
Systolic pressure too high or diastolic
pressure too low.
Assess EV1000 system starting from patient leading to
Finger Cuff and Pump-Unit.
Check the arterial waveform for severe hypotension,
severe hypertension, and motion artifact.
Make sure the heart end of Edwards HRS is aligned with
the patient’s phlebostatic axis.
Confirm electrical connections of cables.
Apply Finger Cuff to a different finger.
Resize Finger Cuff and replace Finger Cuff with different
size.
Alert: Unstable Blood Pressure
Signal
Arterial waveform is inadequate to
measure CO accurately.
Systolic pressure too high or diastolic
pressure too low.
Assess EV1000 system starting from patient leading to
Finger Cuff and Pump-Unit.
Check the arterial waveform for severe hypotension,
severe hypertension, and motion artifact.
Make sure the heart end of Edwards HRS is aligned with
the patient’s phlebostatic axis.
Confirm electrical connections of cables.
Apply Finger Cuff to a different finger.
Resize Finger Cuff and replace Finger Cuff with different
size.
Fault: SVV - Check Blood
Pressure Waveform
Arterial waveform is inadequate to
measure SVV accurately.
Poor pressure waveform over extended
period of time.
Frequent Physiocals within waveform.
Systolic pressure too high or diastolic
pressure too low.
Assess EV1000 system starting from patient leading to
Finger Cuff and Pump-Unit.
Check the arterial waveform for severe hypotension,
severe hypertension, and motion artifact.
Make sure the heart end of Edwards HRS is aligned with
the patient’s phlebostatic axis.
Confirm electrical connections of cables.
Apply Finger Cuff to a different finger.
Resize Finger Cuff and replace Finger Cuff with different
size.
Fault: Battery Depleted The battery is depleted and the system will
shut down in 1 minute if not plugged in.
Connect EV1000 NI to an alternate source of power to
avoid loss of power and resume monitoring.
Alert: Low Battery
The battery has less than 20% charge
remaining or will be depleted within 8
minutes.
Connect EV1000 NI to an alternate source of power to
avoid loss of power and continue monitoring.
Alert: Battery Information
Unavailable
Previously connected Pump-Unit not
detected.
Poor Pump-Unit Ethernet connection.
Confirm Pump-Unit Ethernet connection.
Disconnect and reconnect Pump-Unit Ethernet cable.
Change Pump-Unit Ethernet cable.
If problem persists, contact Edwards Technical Support.
