In a normal subject the pressure at the ankle is slightly higher than at the elbow (there is reflection of the pulse pressure from the vascular bed of the feet, whereas at the elbow the artery continues on some distance to the wrist). [citation needed] The ABPI is the ratio of the highest ankle to brachial artery pressure.
In adults, a normal blood pressure is 120/80, with 120 being the systolic and 80 being the diastolic reading. [12] ... (see Ankle brachial pressure index).
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.
What is a normal blood pressure reading? Updated May 17, 2019 at 1:19 PM. ... "Your blood pressure is supposed to be under 140 over 90, optimally closer to 120 over 80."
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
The ankle-brachial pressure index compares the systolic blood pressure of the ankle to the systolic blood pressure of the arm. A ratio that is outside of the range of 1-1.3 may indicate a disease of the vessels, such as peripheral arterial disease (the ankle-brachial index would be low). [1]
A patient's ankle brachial pressure index (ABPI) must be >1.0 per leg to wear compression stockings, otherwise the stockings may obstruct the patient's arterial flow. The ABPI indicates how unobstructed a patient's leg and arm arteries are.
