Final answer:
The Ankle-Brachial Index (ABI) is a test used to assess peripheral vascular disease (PVD). The normal ABI range is typically between 0.90 and 1.30.
Step-by-step explanation:
The Ankle-Brachial Index (ABI) is a simple and non-invasive test used to assess peripheral vascular disease (PVD). It compares the blood pressure in the ankles to the blood pressure in the arms. The normal ABI range is typically considered to be between 0.90 and 1.30. An ABI value below 0.90 indicates the presence of PVD, while a value above 1.30 may suggest calcification or stiffening of the arteries.
