A

ABI compares systolic blood pressure at the ankle and arm to check for peripheral artery disease.

Measure UE systolic BP at the brachial artery and LE systolic BP at posterior tibial and dorsalis pedis arteries

ABI is calculated by dividing the higher of the two BP measurements in the ankles by the higher of the two systolic BP measurements at the arms

< 0.9 = moderate blockage; maybe associated with intermittent claudication
< 0.5 = severe blockage and arterial disease; may have claudication pain at rest

  2. Release the pressure
  3. Observe the time for the nail or skin to regain its full color
Normal = full color returns in < 2 seconds
Abnormal = refill time > 2 seconds

(Take HR and SBP during the same exercise workload)
