Evaluation of peripheral arterial occlusive disease with arterial oscillograph prototype

Abstract

Arterial oscillography (AO) is a non-invasive pneumatic technique for measurement of blood volume changes inside an organ or body part. In presented study, a peripheral arterial disease (PAD) of 19 individuals (35 legs) was measured using AO prototype instruments. The results of AO evaluation were compared to results of computed tomography angiography (CTA), which is the gold standard for diagnosis of PAD. The sensitivity and specificity of AO prototype instrument in amount of 79% and 81%, respectively was calculated.
