The ABPI is the ratio of the highest ankle to brachial artery pressure. An ABPI between and including 0.90 and 1.29 considered normal (free from significant PAD), while a lesser than 0.9 indicates arterial disease. [14]
Ankle-brachial pressure index (ABPI) assesses peripheral vascular disease. [1] It may however be unreliable in patients with calcified arteries in the calf (often diabetic patients) or those with extensive oedema, in which case toe pressure or Toe-brachial pressure index (TBPI) should be measured to aid in the diagnosis.
Ischemia is graded 0 through 3 based on ABI, ankle systolic pressure, and toe pressure. [66] Grade 0: ABI ≥0.80, ankle systolic pressure ≥100 mm Hg, toe pressure ≥60 mm Hg; Grade 1: arterial brachial index 0.6 to 0.79, ankle systolic pressure 70 to 100 mm Hg, toe pressure 40 to 59 mm Hg; Grade 2: ABI 0.4–0.59, ankle systolic pressure 50 ...

In adults, a normal blood pressure is 120/80, with 120 being the systolic and 80 being the diastolic reading. [12] Usually, the blood pressure is read from the left arm unless there is some damage to the arm. The difference between the systolic and diastolic pressure is called the pulse pressure.

Additionally, it is omitted when the patient is demonstrating hemodynamic instability, [2] which term is generally used to indicate abnormal or unstable blood pressure but which can also suggest inadequate arterial supply to organs. [6] Orthostatic vital signs are also taken after surgery. [7]
