2. LOWER EXTREMITY DOPPLER ARTERIAL
WAVEFORM PATTERN ANALYSIS
The Doppler arterial waveforms obtained from the lower extremity may be classied into six
categories as an aid in interpretation.
TYPE TYPICAL WAVEFORM FINDINGS
0 The contour exhibits a steeply rising upslope at the onset of systole,
rapid systolic downslope, and reverse ow (below baseline). Dop-
pler sounds are loud and sharp. Normal peak forward velocity = 30
+/- 10 cm at the dorsalis pedis artery.
I The contour demonstrates a strong but diminished systolic compo-
nent and loss of reverse ow. The width of systolic pulse is broad-
ened. The Doppler sounds are diminished very little as compared
to the type “O” pattern.
II The contour shows prolongation of both the upstroke and the down-
stroke and diminished waveform amplitude (attening). Doppler
sounds are heard during systole and continuing through all or most
of diastole.
III The contour exhibits slowly rising velocity during systole, and the
amplitude of the waveform is reduced. Doppler sounds are not
sharp even during systole.
IV The amplitude of the waveform and the Doppler sounds is greatly
reduced.
V The amplitude of the waveform is extremely reduced. The contour
is hardly recognizable as an arterial blood ow waveform. The
Doppler sounds are very faint.

abdomen during monitoring.
6. The LCD will show the monitoring waveform and
numerical heart rate. Press the probe button or Right
button to freeze the waveform. Up to 33 minutes of
FHR monitoring can be displayed over 4 LCD screens
(approx. 8 minutes per screen). If you would like
to save the data in memory, see 6-2-1 “MEMORY -
