screen in Realtime mode. A single Flowprobe is connected as seen by the Q1 channel on the left side. Ultrasonic
signal coupling is good as indicated by the ve green bars. Pressure and ECG signals are connected.

Operation
A. Realtime Mode: Realtime Display of Flow Waveform & Data
A typical realtime display will include (Fig. 6.2):
1) Q1: Flow Waveform with diastolic lling in blue and systolic lling in red
2) Mean Flow over eight seconds in mL/min. The mean ow line is shown in green on the waveform.
3) Pulsatility Index (PI):
PI =
Maximum Flow-Minimum Flow
Mean Flow
4) Diastolic Fraction (DF) is interchangeable with D/S Flow Ratio (see page 17). For further description of
the D/S Ratio and DF, see Appendix C: ECG Signal, D/S Ratio & DF, page 39.
5) Signal Strength displayed as colored bars.
6) Pressure signal if connected.
7) ECG signal at the bottom of the screen if connected; colorized to indicate systole and diastole.
