Vascular Testing Instructions
2. SEGMENTAL BLOOD PRESSURES
Segmental pressure studies are performed with the same method as an Ankle Brachial Index, but
incorporate additional cuffs wrapped above and below the knee, and optionally at the high thigh, in
additional to the ankle. Significant pressure differences between adjacent cuff sites indicate narrowing
of the artery or blockage in that portion of the leg. Segmental pressures are useful to precisely identify
the location of blockages in the arteries of the leg.
Prepare the Patient
Place the patient in a supine position. Wrap appropriately sized blood pressure cuffs around
each leg at the ankle, above and below the knee, and, if necessary, at the high thigh. Connect
one end of the tubing to the ankle cuff and the other end to the inflation inlet on the front of the
unit.
Take a blood pressure reading at the arm
Follow the steps for taking a blood pressure reading at the arm
as described in the instructions for performing an Ankle Brachial
Index
.
Take the systolic pressures at the leg
Before taking the systolic pressures at the leg, take printouts of the Doppler waveforms at the
Dorsalis Pedis, Posterior Tibial, Popliteal and Femoral arteries by following the instructions for taking
a waveform printout as described in
4-5 “MEASURING BLOOD VELOCITY” for details.
1. After documenting the waveform
s, press the MODE
button until the Arm/Leg pressure mode is selected.
3.
Apply ultrasound gel to the
dorsalis pedis artery.
Place the Doppler probe (pencil style) on the artery at
a 45 to 60 degree angle against flow. Adjust the probe
angle until best sounds are heard and a steady waveform
appears on the LCD.

CAUTION
Use ultrasound gel. Other materials such as baby oil or cream may produce incorrect
sounds or damage the probe.
WARNING
The ultrasound gel included with purchase is non-sterile and should only be used
noninvasively.
WARNING
Discontinue use of ultrasound gel if an allergic reaction occurs.
CAUTION
The probe transducer tip is thin and delicate. Please
handle with care and use the probe cap when not in
use.
