The<unk>  (ABPI) or<unk><unk><unk>  (ABI) is the ratio of the blood<unk>  at the<unk>  to the blood<unk>  in the upper arm (brachium). Compared to the arm, lower blood<unk>  in the leg suggests blocked arteries due to peripheral artery disease (PAD). The ABPI is calculated by dividing the systolic blood<unk>  at the<unk>  by the systolic blood<unk>  in the arm.
