Protocol Card
Pouch
The Protocol Card Pouch provides convenient storage for protocol cards that are
not in use. The Protocol Card Pouch may be hung on the two rear bag pins lo-
cated on the Protocol Card door side of the MCS+ device.

ALVES
There are seven color-coded valves on the MCS+ device deck. The operation of
the valves is automatic. Specific valve functions are discussed in the protocol
sections.
During power-up, the system performs tests on all of the valves. After a protocol
has been selected, the appropriate valves are opened to accept the disposable
and their active indicators are illuminated. To open a valve, simply toggle the le-
ver on the top of each valve. It is not normally necessary to open a valve this way
unless you wish to reposition a section of tubing.
Note: Do not interfere with machine operation of any of the valves unless the
pumps are stopped or the machine is in the Ready mode. (This occurs if the
pumps are temporarily stopped or if the red STOP key on the control panel has
been pressed.) Attempting to manually alter the state of any of the valves during
normal machine operation causes the system to alarm.

ONITORS
Donor Pressure
Monitor (DPM)
The Donor Pressure Monitor (DPM) is an electronically controlled pressure mon-
itor that regulates the speed of the pumps by providing feedback about the flow
to and from the donor/patient.
Pressure is measured in the donor/patient line through a hydrophobic bacterio-
static filter on the disposable set. The DPM monitors pressures as low as -80
mmHg during Draw and as high as +260 mmHg during Return. This information
is processed by the computer and displayed via a bar graph on the display
screen.
Draw Mode
During Draw, the high end of the bar graph represents a pressure of +50 mmHg,
and a low end represents -50 mmHg. The lowest DPM limit during Draw of -80
mmHg is not displayed on the bar graph.
