System Malfunction and Pump Shutdown
Specific patient states, operating conditions or pump malfunctions can cause shutdown
of pumping action. The AutoCAT 2 has internal diagnostic mechanisms to notify you of
®
console or catheter malfunctions. The possible causes and suggested corrective actions will
be displayed on the LCD. It is important to pay attention to alarms and to respond
immediately if the pump shuts down. If the pump shuts down, the balloon will deflate
automatically. However, allowing a deflated balloon to remain dormant is hazardous. A
deflated balloon does not provide valuable cardiac support to the patient and thrombus
formation can occur if blood becomes trapped in the folds of the deflated balloon.
WARNING
Pump shutdown requires immediate staff action. Note the time and call knowledgeable maintenance
personnel. If pumping cannot be restored within 15-30 minutes, manually inflate and deflate the IAB
several times per hour to reduce the risk of thrombus formation. Consider removing the balloon.
Arrow International recommends that you have a back-up IABP system available.
If a pump shutdown occurs, note the time and call hospital personnel knowledgeable in
the maintenance of the The AutoCAT ® 2. If repair and pumping cannot be accomplished
within 15-30 minutes, use a 50/60 cc syringe to rapidly inflate and deflate the balloon
several times per hour. This will reduce the risk of thrombus formation, but should be
used only as an emergency procedure for short periods of time while awaiting the
physician's arrival. The physician should consider removing the balloon. Arrow
International, Inc. recommends that you have a back-up IABP system available in case
of a pump shutdown.
Chapter 8 contains troubleshooting tables to help you identify and correct problems
quickly. If you are unable to correct a problem with your system, call your Arrow
International Representative or the Product Support Line for assistance.
