Q

Know how to calculate ABIs (pressures will be given)

A

Divide the ankle pressure from the highest of the brachial pressures.

> 1.35 = probable calcified arteries
0.90 - 1.35 = normal
< 0.90 = abnormal, stress test appropriate
< 0.8 = probable claudication
< 0.5 = multi-level disease or long segment occlusion
< 0.3 = ischemic rest pain - severe disease
