WebFeb 26, 2024 · An ABI ratio between 0.9–1.4 that is correlated with a multiphasic waveform (e.g., triphasic or mild biphasic) is consistent with a patient who does not have arterial occlusion. An ABI between 0.7–0.9 should correlate with biphasic waveforms (e.g., mild or weak biphasic). These waveforms have a sharp upstroke to the peak and one pit.
