ABI
Also written as: ABI — ankle-brachial index
Ratio comparing blood pressure in ankle to arm, used to diagnose peripheral arterial disease.
Full Definition
Ankle-brachial index is a non-invasive diagnostic test that compares systolic blood pressure measurements at the ankle and arm to assess for peripheral arterial disease. Normal values range from 0.9-1.3, with values below 0.9 indicating arterial insufficiency. This measurement is fundamental in vascular surgery documentation and requires consistent formatting and interpretation guidelines in clinical reports.
Usage
Usage note: Always hyphenate the full form as 'ankle-brachial index'.
