Toe pressure and TBI<\/h1>\n\n\n\n

Toe pressure and TBI are noninvasive macrocirculation measurements for evaluating blood perfusion in the toes, providing critical insight into vascular health. Toe pressure measurements are useful in wound healing, detecting and managing peripheral artery disease (PAD) and chronic limb-threatening ischemia (CLTI) \u2014 especially when ankle pressure may be unreliable due to noncompressible arteries.<\/p>\n\n\n

Toe pressure versus TBI<\/h2>\n\n\n\n

Toe pressure is the absolute measurement of local blood perfusion in the toes and its thresholds are used in a variety of clinical assessments. TBI is the ratio of toe pressure to brachial (arm) pressure. By accounting for variations in systemic blood pressure, TBI normalizes toe pressure which helps clinicians interpret low toe perfusion values. <\/p>\n\n\n <\/div>\n <\/section>\n\n\n

Clinical significance of toe pressure<\/h3>\n\n\n\n

The small arteries in the toes are less likely to be calcified than larger vessels like those in the ankle [1]<\/a><\/sup>. This makes toe pressure and TBI measurements useful when diagnosing patients with diabetes or chronic kidney disease \u2014 where arterial calcification can render ankle-brachial index (ABI) measurements inaccurate.<\/p>\n\n\n\n
