2. Fig 1
Triphasic: three waveform “phases” consist of a sharp systolic forward up rise and fall, an element of reverse flow during diastole, and an element of forward flow during diastole.

3. Fig 2
Biphasic: two waveform “phases” consist of a sharp systolic forward up rise and fall, and an element of reverse flow during diastole.

4. Fig 3
Sharp monophasic consists of a sharp systolic rise, the lack of a reverse diastolic element, and a fast diastolic fall.

5. Fig 4
Poor (blunted) monophasic waveform shows the loss of “sharpness” in systole, the lack of a reverse diastolic element, and a slow diastolic fall.
