When the Assess Blood Flow screen first opens, the only selectable button is 7a, Collect Baseline .
When in the baseline or assessment state, the user must wait a minimum of 30 seconds before
being able to select the button to continue to the following state.
4. The Waveform Display Scale allows the user to increase or decrease the scale of the x-axis (time)
on the waveform display
5. The Waveform Display covers the upper half of the screen and is a large plot where the incoming
information from the FloPatch is graphed in real time. The waveform streams from the left side of

mode and blue when in REV mode.
