10.2 Switching to another Pump
WARNING
DO NOT restart the Pump if it has stopped due to Motor overheating.
Overheating is confirmed by a MOTOR OVER TEMP alert message and
temperature sufficient to prevent the user from placing and holding a hand on
the Motor housing. Clamp the return tubing and switch to the backup System
according to the procedure described in Section 10.1. Resume support. Record
the alarm message and contact your local Abbott Medical representative.
WARNING
Always fully unscrew the Pump retaining screw built into the Motor before
inserting and locking the Pump in the Motor receptacle. This requires five
complete counter-clockwise rotations of the screw. Failure to do so may inhibit
the ability to fully seat and lock the Pump in the Motor receptacle resulting in
loss of function and a MOTOR ALARM or PUMP NOT INSERTED alarm. Should
this condition occur, unscrew the retaining screw, remove the Pump, reinsert
the Pump, tighten the retaining screw, turn the Console power OFF and ON,
ensure no alerts are displayed, and set the Console to begin pumping.
In instances other than Motor overheating, when the Pump has been OFF for more than
five minutes without adequate anticoagulation, it will be necessary to replace the Pump
and other circuit components.
10.3 Defibrillation/ Cardioversion
Defibrillation or cardioversion may be necessary during severe arrhythmias. Cardioversion
may be performed without stopping the Pump. Ensure that a backup Console is available,
powered and in the immediate vicinity.
If cardioversion is attempted without discontinuing support, consideration should be given
to reducing the RPM of the Pump (or Pumps for BVAD support) to reduce the likelihood of
Right-Left imbalance and Pump inlet obstruction. Following cardioversion, slowly increase
the VAD RPM (or resume BVAD support) while monitoring the patient's hemodynamics to
ensure adequate volume available for the desired flow.
WARNING
During cardioversion, ensure the backup Console, Motor and Flow Probe is on
and prepared for use in the event of main Console malfunction. After
defibrillation or cardioversion is performed, ensure that the main Console is
working correctly and return the backup Console to the AC Off condition.
