Abstract

Deep Vein Thrombosis (DVT) is a condition that leads to the formation of blood clots in the deep veins. Swelling or pain inthe lower limb is a common symptom thatgenerally affects the deep veins in the leg. Pulmonary Embolism (PE) is the most dangerous complication of DVT. It occurs when blood clots migrate from the deep veins of the legs to the lungs. Various invasive and non-invasive methods can be utilized to detect DVT. Among them, Impedance Plethysmography is one of the non–invasive methods, which uses an occlusive cuff. This could cause separation of possible thrombus due to downstream venous pressure, resulting in PE. Hence, this paper aims to design and develop an Impedance Plethysmography (IPG) System without an occlusive cuff to detect DVT. Also, the proposedcost-effective systemaims to provide noise-free IPG signals. These signals will be further processed to identify the DVT through Matlab software.

The observations on subjects have shown an increasing impedance withreduced blood volume due to limb rise. However, the impedance decreases when the limb is returned to its resting position. While the limb is returned to its initial position, the subjects with DVT have a longer blood-filling timethan expected, especially for the affected leg. Moreover, the proposed methodology is validated with 30 subjects, and its efficacy is endorsed by calculating performance measures like sensitivity and specificity.
