Leycom® CFL-512 and Conduct NT

CD Leycom September 2004

The LEYCOM® Cardiac Function Lab CFL-512 facilitates the on-line
measurement and analysis of ventricular pressure and volume signals in clinical
setting. The pressure and volume signals are obtained using a combined
conductance and pressure catheter. The CFL-512 acquires and displays these
signals on-line and continuously. The signals are digitized, stored and can be
subsequently played back and analyzed the users convenience.

CFL-512 is a stand-alone device, which can be easily used in

different clinical environments. The system, including the software for data
acquisition and analysis, has been developed in close co-operation with a group
of clinical users of Leycom

equipment.

The bedside 'patient module' is a state of the art, battery powered, data
acquisition module. The module, to which the conductance catheter is
connected, contains sophisticated circuitry, which ensures optimal patient safety
and extended battery life.
The 'patient module' is communicates with the Leycom
a fibre optic cable; this provides complete patient isolation from electrical
hazard.

is Intel Pentium based, has a 40 Gb harddisk, enough
for hundreds of hours of data acquisition, at 12 channels and 250 samples per
second.

With the Leycom

®

CFL-512 software, time-varying ventricular volume,

pressure, ECG, a large number of hemodynamic variables and Pressure-volume
loops can be displayed. The slope and intercept of the end-systolic pressure­volume relation (a measure of ventricular performance) are calculated, as well as
other related variables.
