Just curious. If you have reflux that goes on and on, how do you document that? If it is obviously say >5 sec., do you just do a measurement on a single spectral image from the point of augmentation (say X amount of sec.) then report it as >5 sec. which obviously is abnormal.
There is someone who used continuous as a criteria, because the IAC had issue with that documentation. It was apparent by the spectrum that the reflux exceeded the required time for clinically significant disease, but the criticism was the term continuous vs. an absolute time (obtained by calipers).
Thanks for your help with trying to get the correct terminology.

We routinely measure reflux time with our GE E9 machines by means of electronic calipers. We had them make a quantity button for us so it really doesn’t had much time to our protocol.

Received a response from IAC critical of our venous studies because we don’t use the electronic calipers to measure reflux time. We don’t because the time scale is easily seen on the spectrum and the physician
can use that as well as the sonographer can, because having to make this measurement on say 30 spectra collected on a bilateral LE reflux exam would add unnecessary sonographer time to the exam, and because we’re not even sure that the iU22 will measure time.
I have never seen time measured using the electronic calipers on any duplex exam. Does anyone else do this? On what type of scanner?
Thanks
