Ankle-Brachial Index (ABI) - correct answer ✔✔A ratio derived by dividing the ankle blood pressure by

To obtain the ABI, a blood pressure cuff is applied to the lower extremities just above the malleoli. The
systolic pressure is measured by Doppler ultrasound at both the dorsalis pedis and posterior tibial pulses.
The higher of these two pressures is then divided by the higher of the two brachial pulses.
>1.2 - possible calcification in vessel walls
1-1.2 - Normal
.9-.99 - acceptable
.8-.89 - some arterial disease
0.5-0.79 - moderate arterial disease (intermittent claudication)
<0.5 - severe disease, ischemia
