Alert
Alert
System will not start. An audible alarm will sound, which can be muted for 60 seconds. Press the alarm acknowledge button. Insert or reinsert the pump and secure it with the locking screw. If the alarm repeats, switch to backup Console, Motor and Flow Probe according the procedure described in Section 2. An audible alarm will sound and the System will continue to operate. Press the alarm acknowledge button, if the visual alarm message does not disappear, clamp the return tubing, stop the pump and switch to the backup Console, Motor and Flow Probe according the procedure described in Section 2. Resume support. Record the alarm message and contact your local Abbott Medical representative. Check the Pump flow. If pump flow is satisfactory, reduce set speed while insuring that flow is maintained. Press the alarm acknowledge button. If the alert repeats, clamp the return tubing, stop the pump and switch to the backup Console, Motor and Flow Probe according the procedure described in Section 2. Resume support. Record the alert message and contact your Abbott Medical representative. If the pump flow is not satisfactory, clamp the return tubing and switch to the backup Console, Motor and Flow Probe according to the procedure described in Section 2. Resume support. Record the alert message and contact Abbott Medical representative.
RESPONSE TO SYSTEM ALARMS OR ALERTS
When a System alarm or alert condition occurs, an alarm or alert tone sounds and text message appears on the display of the 2nd Generation CentriMag Primary Console. Most alarms and alerts require some action on the user’s part to correct the cause. The following table can be used to determine how to respond to an alarm or alert condition.

Alert
FLOW SIGNAL INTERRUPTED (Flow rate sensor error)
FLOW BELOW MINIMUM (Low Flow)
Manually disconnect, reposition and reconnect the Flow Probe transducer to the tubing. Press the alarm acknowledge button. Switch to the backup Flow Probe, if the alert message repeats. If problem still persists after switching to the backup Flow Probe, stop the pump and switch to a backup Console. Follow the instructions described in Section 2. Resume support. Record the alert message and contact your Abbott Medical representative.
Check for physiologic cause or circuit obstruction. Check minimum flow set point. Do not increase RPM without confirming that adequate blood volume is available. Common cause of this alert is inadequate blood volume at the drainage cannula site for the desired pump flow.
FLOW ABOVE MAXIMUM
Reduce Pump speed and check for cause.
Alert
PRESSURE 1 DISCONNECTED
Check the electrical connections on the pressure 1 transducer and recalibrate. If the problem persists disconnect, reconnect, and recalibrate the transducer. Consider changing the transducer and cable if the problem persists.
Alert
PRESSURE 2 DISCONNECTED
Check the electrical connections on the pressure 2 transducer and recalibrate. If the problem persists disconnect, reconnect, and recalibrate the transducer. Consider changing the transducer and cable if the problem persists.

Alert
PRESSURE SYSTEM FAIL
The pressure monitoring system will not function. If pressure monitoring is needed then change to the backup Console, Motor and Flow Probe. Switch to the backup System according the procedure described in Section 2. Resume support. Record the alert message and contact your Abbott Medical representative.
Alert
PRESSURE 1 BELOW MINIMUM
Check for and resolve a physiological or mechanical cause. Ensure appropriate pressure alarms are set. Consider recalibrating the transducer, if alert cannot be explained by conventional troubleshooting.
Alert
PRESSURE 2 BELOW MINIMUM
Check for and resolve a physiological or mechanical cause. Ensure appropriate pressure alarms are set. Consider recalibrating the transducer, if alert cannot be explained by conventional troubleshooting.
Alert
PRESSURE 1 ABOVE MAXIMUM
Check for and resolve a physiological or mechanical cause. Ensure appropriate pressure alarms are set. Consider recalibrating the transducer, if alert cannot be explained by conventional troubleshooting. Consider reducing RPM to reduce the pressure if appropriate.
P7
Alert
PRESSURE 2 ABOVE MAXIMUM
Check for and resolve a physiological or mechanical cause. Ensure appropriate pressure alarms are set. Consider recalibrating the transducer, if alert cannot be explained by conventional troubleshooting. Consider reducing RPM to reduce the pressure if appropriate.

Alert
MOTOR OVER TEMP
Switch to backup Console, Motor and Flow Probe according to the procedure described in Section 2. Verify that the backup Motor stands free and is not covered (e.g. blankets).
B3
Alert
BATTERY CHARGER FAIL
Press the alarm acknowledge button. If the alert message repeats, switch to backup System as described in Section 2. If this alert is associated with BATTERY MODULE FAIL then carry out the procedure associated with that alarm.
Alert
BATTERY MAINTENANCE REQUIRED
Do not use the Console. Perform battery maintenance according to the Battery Maintenance Procedure listed in the CentriMag Circulatory Support System Operation Manual.
Alert
LOW BATTERY
Plug the Console into a AC power outlet to charge the battery. If no AC outlet is available, switch to the backup Console, Motor and Flow Probe according to the procedure described in Section 2. Resume support.
Alert
ON BATTERY
Verify that the user wants the Console to be on battery. If so, carefully monitor the status of the battery charge indicator, while using the System on battery. Reconnect to AC-outlet, as soon as possible.

SWITCHING TO BACKUP HARDWARE
Switch all components (Console, Motor, Flow Probe and cables) simultaneously and then perform troubleshooting on the non-functioning System when it is no longer being used for patient support. The steps to switch to a backup Console, Motor and Flow Probe set are as follows: 1
Clamp the return tubing (outlet side).
2
Continue clamping the tubing while lowering the RPM to zero. Turn the main Console’s power switch off. Turn on the backup System, and make sure that it is properly assembled with the backup Motor.
3
Unthread the Pump retaining screw on the Motor by turning the screw counterclockwise several revolutions until the screw tip is clear of the locking groove on the Pump.
4
Rotate the Pump body clockwise until the grooves in the Pump match the Motor. Lift the Pump from the receptacle.
5
Place the Pump in the backup Motor receptacle (the Pump will drop into place in one of 3 orientations).
6
Rotate the Pump counterclockwise until it stops.
7
8
Thread the Pump retaining screw to secure the Pump in place by turning the screw clockwise until it stops. Confirm that the retaining screw is visible in one of the notches on the side of the pump. If the retaining screw is not visible in a notch, loosen the retaining screw, remove the pump, remount, rotate the Pump counterclockwise, and secure by advancing the retaining screw. Pumping operation may now be re-established via the backup Console by increasing the RPM to about 1000 RPM. Gradually increase RPM while unclamping the Pump outflow tubing. Continue to gradually increase the RPM to achieve the desired flow. Pumping operation should be returned to the last operating condition of the Pump. Be sure to reset options and alarms to match those selected before hardware exchange.
If the Pump has been OFF for more than five minutes without adequate anticoagulation, or if there has been a Motor Overheating condition, it will be necessary to replace the Pump and circuit, including cannulae. NOTE: To be available for emergency use, the backup Console, Motor and Flow Probe must be transported with and in proximity of the main Console and Motor, and plugged into AC power, with the main power switch OFF. The battery power for the backup Console must be periodically assessed by turning the main power switch ON, checking the status of the battery, and then turning the main power switch OFF. In addition, the expiration date and maintenance due date of the backup Console’s Battery, must be checked on a periodical basis. For additional information, refer to the CentriMag Circulatory Support System Operation Manual.
