Emergency / Troubleshooting; Switching To Backup Hardware - Abbott CentriMag Operation Manual

10 EMERGENCY / TROUBLESHOOTING

This section contains instructions for operation of the Pump during external defibrillation,
and under circumstances where there is a need to exchange the main Console or Motor
with a backup Console or Motor.
The recommended practice whenever there is a Console or Motor malfunction is to
replace the Console and Motor as a set. Remove the Pump from the malfunctioning Motor
and Console and place the Pump in the backup Motor and Console to continue patient
support. DO NOT exchange individual Motors or individual Consoles during patient
support.
WARNING
A Pump stoppage will create a reverse flow shunt, as well as limit the body's
ability to maintain adequate arterial pressure. If the Pump is off, clamping the
Pump outlet cannula or tubing is necessary to prevent a low flow, low pressure,
or reverse flow condition. The tubing clamp must be removed before returning
to normal pumping activity.

10.1 Switching to Backup Hardware

A backup Console, Motor and Flow Probe should be transported with the patient and
immediately available for use at all times. Should the main Console or Motor cease to
function, it will be necessary to replace the hardware by disconnecting the Pump from the
main Motor and Console and switching to a backup Motor and backup Console. Switching
to a backup Console and Motor is performed in accordance with the steps shown in
Figure 63. 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.
To switch to a backup Console and Motor set:
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) 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.
