I can't recall a situation where the flow reverted to prograde as the cuff pressure was reduced, i.e., it has always stayed retrograde if it started retrograde, so I would not have expected to face this question. Has anyone else seen this?
The goal is to measure the pressure at the point of the cuff so as soon as there is any flow, one has to assume that the blood pressure is at least equal to the cuff pressure, I think I would vote to take the pressure when you see any flow.

Subject: ABI ankle pressure question
At the ankle, if the waveform returns as a retrograde wave form should you take that as the pressure reading or wait until it returns to antigrade and why so0?
