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
A Pump stoppage will create a reverse flow shunt, as well as limit the body’s
ability to maintain adequate arterial pressure. Clamping the Pump outlet tubing
is necessary to prevent a low flow or low pressure incident in a Pump-off
scenario. The tubing clamp must be removed before returning to normal
Pumping activity.
WARNING
DO NOT clamp, partially clamp, or restrict the tubing during normal Pump
activity. Clamping the tubing may cause increased risk of thromboembolic
events.
WARNING
Monitor 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 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.
To restart the Pump, perform the following steps:
1. Ensure that the Pump is securely located in the Motor per the Instructions for Use
supplied with the Pump.
2. Ensure that any alarm condition has been corrected.
3. 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.
4. Slowly increase the RPM until the flow rate is at the desired level.
The
RPM
and
LPM
will be displayed on the Console.
