8 SYSTEM OPERATION
This section describes the operation of the Console including starting and stopping the
Pump and adjusting the Pump speed. This section also contains information on the
System parameters, alarms and battery operation for patient transport.
Prior to starting the Pump, the Flow Probe cable must be connected to the Console and
the Flow Probe attached to the return tubing. Clamp the Pump outlet or return tubing to
prevent retrograde flow before connecting the extracorporeal circuit to the Cannulas and
prior to turning the Pump ON.
8.1 Operation of the Pump
WARNING
Monitor the patient’s hemodynamics and the Console flow display to ensure the
patient has adequate blood volume that the drainage cannula is properly
positioned, the Pump RPM is appropriate, and the desired flow is achieved.
Increase Pump RPM in small increments to minimize the risk of exceeding the
available blood volume and causing drainage cannula obstruction.
CAUTION
The Console, Monitor, Mag Motor, and Flow Probe are not sterile and cannot be
sterilized. Do not use the Console, Monitor, Motor, and Flow Probe inside of the
sterile field or in a location where they may come into contact with items that
must remain sterile.
8.1.1 Starting the Pump
To start the Pump, perform the following steps:
1. Place the Pump into the Motor receptacle and secure in place per the Instructions for
Use supplied with the Pump.
2. Start the Pump by first depressing the
SET RPM
keypad.
SET PUMP SPEED = 0000
RPM
will be displayed. Depress the
INCREASE
keypad and increase the RPM to a
level sufficient to overcome the Pump afterload (>1000 RPM for large return cannula
or low arterial pressure and >1600 RPM with small return cannula or high arterial
pressure) while slowly unclamping the return tubing. Higher RPM’s (>1800 RPM) may
be required with very small Cannulas.
3. Slowly increase the RPM until the flow rate is at the desired level.
The
RPM
and
LPM
will be displayed on the Console display.
Note: Always set the
MINIMUM FLOW ALERT
to the desired minimum flow level as soon
as possible after initiation of support by following the instructions provided in
Section 7.10.
WARNING
Depressing opposing inputs to the Monitor and Console at the same time, such
as depressing the UP arrow on the Monitor and the DOWN arrow on the
Console, will result in no change in the Console, consistent with no input.
