Cardioplegia Shared Channel - CardioQuip MCH-1000 Operators & Service Manual

Cardioplegia Shared Channel

The CPG Module controls are only visible if the Cardioplegia Shared Channel Module
(MCH-10CSC) is installed, and offer the following operational modes:
Off Water does not flow through the CPG circuit.
Water is circulated directly from the MCH water tank through the CPG circuit by a
secondary water pump. The temperature of the water in the CPG circuit is determined by
the temperature of the water in the water tank. This mode is designed to deliver cold
Cold
cardioplegia, and may be used as a water source for the Quest MPS™. If the MCH is
delivering water in STANDBY mode (so the primary water pump is not running), this
button will blink.
The CPG circuit is connected to the Main circuit, and the secondary water pump is off.
Water is circulated through the CPG circuit at the same temperature as the Main circuit.
This mode is useful for delivering a "warm shot" at the end of a procedure, or for
connecting a patient blanket. Switching from "Cold" to "Main" may cause a short-term
Main
temperature fluctuation in the Main circuit, due to the introduction of water from the CPG
circuit. In order to reduce this fluctuation, the MCH will automatically pre-heat the internal
heaters for approximately ten seconds before making the switch. To further minimize the
fluctuation, reduce the overall length of the CPG circuit tubing as much as possible.
