Project Ankle-Brachial Index: Implementation Of An Evidence-Based Peripheral Artery Disease Protocol, Melaney Banks

Doctor of Nursing Practice Projects

Background: Peripheral artery disease (PAD) is a narrowing or blocking of the arteries due to plaque buildup, which prevents oxygen, blood, and other nutrients from getting to the legs. When this buildup reaches a certain point, it becomes atherosclerosis, which is more prevalent in a smoker. Smoking intensifies the problem of plaque buildup if an individual already suffers from PAD. When an individual smokes, the nicotine causes the arteries to constrict and narrow, reducing blood flow further. The ankle-brachial index (ABI) is a simple, cost-effective diagnostic test to identify the presence of PAD which will improve patient outcomes.

Purpose: This …
