ABI
This is a ratio that compares and divides the LE pressure by the UE pressure to help determine if there is a vascular problem
ABI is performed with patients who have _____
arterial dx to determine if the lower extremity is getting enough blood and oxygen
**this will help determine if a wound will heal well
What UE pulse is used for ABI
brachial
What LE pulse is used for ABI
dorsal pedis or tibial posterior
Where is dorsal pedis located
lateral to the extensor hallucis longus tendon and is best palpated proximal to the first metatarsal-cuneiform joint
Where is the tibial posterior artery
muscle tendon runs down behind the medial malleolus and end by segregating into main, plantar, and recurrent portions
> 1.2 ABI
indicates non-compliant arteries, falsely elevated, arterial disease, diabetes
0.95-1.2 ABI
normal
0.75-0.94 ABI
mild arterial disease and intermittent claudication
0.50-0.74
moderate arterial disease and rest pain
<0.50 ABI
risk for critical limb ischemia; may have pain at rest, severe arterial disease
