Flow Status Interpretation on the Cell-Dyn 1200
I. RBC and WBC flow status are contained at the bottom of the Data Review screen (under the Utility menu):

Definitions:
Cadence CV: coefficient of variation for RBC or WBC count cadence exceeds 10% or 20% respectively
Voltage CV: coefficient of variation for RBC or WBC electrode voltage cadence exceeds 2% (for both)
Voltage Delta: difference in RBC or WBC electrode voltage between adjacent cadence periods exceeds 2.0V
Voltage Range: absolute RBC or WBC electrode voltage exceeds range of ±30% nominal electrode voltage (Vnom). DC bias of 2.17V is removed from acquired electrode voltage before comparison.
Vnom = Rnom * 1.01mA * [RBC or WBC current set point] / 4096
Rnom = 22.4kW, 22.9kW for RBC, WBC streams respectively
Note: Flow error analysis aborted if electrode voltage does not exceed 1.5V. Cadence CV analysis is aborted if raw cell count does not exceed 2000.
