Non-invasive Venous Air Plethysmography Assessment of Venous Hemodynamics in Suspected Deep Venous Obstruction used in Withth Intermittent Pneumatic Compression.

Overview

About this study

The purpose of this study is to obtain time-series pressure (mmHg) data using a non-invasive pneumatic capture device designed by the Mayo Division of Engineering (DOE) during Mayo Dopplex ABIlity hemodynamic venous compression and intermittent pneumatic compression (IPC) to detect presence of deep venous thrombosis (DVT).
