Systems and Methods For Jugular Vein Measurement Using Ultrasound

Abstract

Systems and methods are disclosed that provide for regular, periodic or continuous monitoring of fluid volume based on direct measurement of dimensions of a jugular vein of a patient using a sensor disposed proximate the jugular vein. Measurements of the jugular vein are made using ultrasound, which may include determination of a two or three-dimensional ultrasound image of the jugular vein. Based on the monitored changes in the jugular vein physical dimensions, information about patient fluid state across the euvolemic range of fluid states can be determined. This may provide earlier warning of hypervolemia or hypovolemia and allow for the introduction or modulation of patient treatments to permit more stable long-term fluid management.
