“…1 Tri-, bi-, and monophasic descriptors were also used to characterize plethysmography waveforms, thereby associating phasicity with changes in volume. 82 Although the inclusion of a zero-flow reference point is inherent to the description of waveform phasicity, 10 21% of the publications had one or more waveform illustrations without a clearly displayed zero-flow reference point. Without this reference, one cannot determine whether a waveform has diastolic flow reversal, reaches zero flow after systole, or has pandiastolic flow.…”

185Doppler instruments are widely used for the noninvasive evaluation of peripheral arterial disease. Auditory descriptors and graphic displays of waveforms characterize the hemodynamics of the vessel being examined. Descriptions of normal Characterization of peripheral arterial waveforms is basic to the diagnosis of vascular disease. Surveys indicate inconsistent application of traditional waveform descriptors. This study reviews literature to identify areas of confusion. Publications were reviewed to determine whether triphasic, biphasic, and monophasic terms were defined; if biphasic was linked with diastolic flow reversal; whether pandiastolic flow was associated with biphasic or monophasic terminology; and whether waveform illustrations had a zero baseline. Ninety-four publications were reviewed. Triphasic and monophasic were defined in 81%, biphasic in 48%. Biphasic was classified with flow reversal in 38%. Pandiastolic flow was not addressed in 57% but associated with monophasic in 47% and biphasic in 5%. Twenty-one percent of the publications had an illustration without a zeroflow baseline. This review suggests a lack of consensus when classifying arterial blood flow with traditional waveform descriptors. Waveform characterization inconsistencies are undermining comprehension of Doppler principles and may lead to inappropriate testing. A multisocietal consensus panel should accept responsibility for resolving this issue.
