Figure 2-4, Donor Flow Lights
The four sets of Donor Flow Lights are located at the top of the panel, the sides
of the cabinet, and the outside of the cover.
These lights indicate status of the flow: Normal (green), Low (yellow), None (red),
or Return (yellow).
NORMAL FLOW
The green lights are illuminated to indicate that the Blood Pump is able to main-
tain a speed greater than 2/3 of the programmed speed. The Blood Pump’s speed
decreases by 5 ml/min each second if the donor/patient pressure falls below -50
mmHg. Once the donor/patient pressure increases again, the pump speed in-
creases at a rate of 5 ml/min each second. This pressure is measured and com-
municated to the MCS+ device computer by the Donor Pressure Monitor (DPM).
LOW FLOW
The yellow Donor Flow Lights are illuminated to indicate that the donor/patient
flow rate is below 2/3 of programmed speed.
NONE
The red light is illuminated to indicate that there is no flow. When the flow stops,
the Blood Pump and AC Pump automatically stop. The Centrifuge continues to
spin to maintain separation. The Blood and AC Pumps automatically restart
when the donor/patient blood flow is restored. The White Pump remains active.
RETURN
During Return, the only donor/patient flow indicator lights that illuminate are
yellow in color and are at the outermost end of the indicator panels.
These yellow lights indicate to the donor/patient and to the operator that the re-
maining components are being returned to the donor/patient.
