Peripheral Vascular Exam: ABPI
How is a ABPI done and what do the results show?
Performed using a pencil doppler machine and a standard blood pressure cuff. Bilateral brachial systolic pressures are recorded and then the highest reading is taken as the denominator for both legs.
In legs, take highest systolic reading from DP and PT to use as the numerator
>1.3 = Unreliable - vessels are calcified, commonly seen in diabetics
0.9-1.8 = Normal range
<0.8 = Evidence of peripheral arterial disease (claudication)
<0.5 = significant peripheral arterial disease - gangrene and ulceration
