Conductance Catheter Settings 
Match the catheter with the actual heart size, exclude individual segments 
and optimize the dual field setting. 
 
 
 
 
 
 
 
Rho measurement 
The Rho cuvette is used to measure blood resistivity from a blood sample. Blood 
resistivity is required for the calibration of the volume measurements. The Rho 
cuvette is connected to the connector on the right side of the CFL-512. When 
the Rho cuvette is filled with 5 ml of blood the display will show the measured 
blood resistivity. By pressing the button next to the display this value is stored 
internally and used in the real-time volume calculation. 
 
 
 
Calibration 
Calibration of the volume signals from the conductance 
catheter is automatic. However, the 6 user defined signals 
connected to the external inputs, Pressure, ECG 2, Aux1, 
Aux2, Aux3 and Aux4 require initial calibration to enable the 
software to convert input signal voltages to user units (e.g. 
mmHg). 
 
Display 
Select display-mode and time-base for an optimal view of your chosen signals. 
View ‘Segmental Volumes’ to check and optimise the (segmental) volume 
signals. Use views with ‘PV-Loop’ to monitor the pressure-volume loops from 
beat to beat. Use views with ‘Indices’ to display real-time the calculated indices. 
Use ‘Dyssynchrony’ view to assess mechanical ventricular dyssynchrony. 
 
 
 
Acquire Data 
Start data acquisition by clicking ‘Acquire’. An audible signal every 1 s 
reminds the user that acquisition is in progress. Stop data acquisition by 
clicking acquire again. Enter a comment at the end of each acquisition run.
