The Clinical Screen (Figure 22) should be used when no pump adjustments or access to other screens is required. Unique
parameters displayed on the Clinical Screen include a real-time power (Watts) waveform and a real-time estimated HVAD
Pump blood flow waveform (L/min). Waveform time scales may be selected for 10 seconds, 20 seconds or 60 minutes.
The waveform time scale may be changed by pressing the "Time Scale" button on the Clinical Screen. Available options
are 10 seconds, 20 seconds or 60 minutes. When the 60 minute option is selected, peak and trough values are displayed
in the lower right section of the screen (Figure 23).
