MOTOR CURRENT WAVEFORM
Motor current is a measure of the energy intake of the Impella
®
RP Catheter motor. The energy
intake varies with motor speed and the pressure difference between the inlet and outlet areas of
the cannula.
The scale for the motor current waveform is displayed to the left of the waveform. The default
scaling is 0–1000 mA. It is adjustable in 100 mA increments for the Impella
®
RP Catheter, with
a minimum difference between upper and lower limits of 200 mA and a maximum difference
of 1000 mA.
To the right of the waveform is a display that labels the waveform, provides the units of
measurement, and shows the maximum and minimum values and the average value from the
samples received. You can set the time scale at the bottom of that window by pressing the
DISPLAY
soft button.
PURGE SCREEN
The purge screen (see Figure 4.5) displays purge system data. In the central display area of the
screen, the purge flow rate and purge pressure are plotted as a function of time. To the right of
the plots, the current purge flow rate and purge pressure are displayed.
Use the
DISPLAY
soft button to navigate to the purge screen.
