ABI with Toe Pressures

Performed to assess the vascular condition of the foot by obtaining systolic pressures at the toe. Toe pressures use an infrared PPG sensor to determine the small vessel vascular condition distal to the ankle. Toe pressures may be useful in cases of unsuspected vascular disease and baseline diabetic foot assessment when falsely high ankle pressure can occur due to calcification. Results are indicators of healing potential in foot ulcers.
