MPS 3 System – Disposable Installation
8.2. Priming and Recirculation
Prior to delivering cardioplegia, the delivery set must be primed to remove all air in the
delivery set and the drug cartridges.
After the disposable is loaded, the MPS 3 System is powered on, and case parameters have
been entered, the MPS 3 System is ready to perform the priming sequence. On completion of
prime the operator has the option to recirculate fluid through the Vent Valve.
When an operator presses the Prime button, the MPS 3 System initiates the priming
sequence. During the automatic priming sequence, the MPS 3 System circulates just enough
cardioplegia solution to clear air bubbles in the delivery line. At the completion of the auto
priming sequence, the manual recirculation mode screen displays.
Prior to starting the priming process, the Arrest Agent and Additive cartridges must be filled. If
a cartridge is not filled a message is displayed giving the operator an option to disable the
specific pump or retest.
To start the Auto Prime sequence, follow the steps outlined below:
1. Select the Prime button on the New Case Setup screen and the start prime screen
displays.
Figure 100: Prime Screen
DO NOT PRIME the delivery set more than 12 hours prior to
surgery. Biological contamination is a risk after more than 12
hours.
When recirculating in Recirc mode or Vent mode, the operator
must ensure that the system has sufficient flow and positive
pressure. If not, the delivery set pouch may drain into the reservoir
which could cause a delay in the next dose of delivery.
