Abstract

Devices, and methods for synchronizing cerebro-hemodynamic signals are disclosed. In one aspect, the devices and methods may include synchronizing first and second signals indicative of hemodynamic characteristics within a subject's brain. Differences may be determined between the synchronized signals and used to provide information for diagnosing changes in arterial occlusion. Differences between the synchronized signals may include differences, such as timing delays, between signature features of the synchronized signals. The first and second signals may be indicative of hemodynamic characteristics in first and second hemisphere's of a subject's brain. The first and second signals may be bioimpedance signals.

Description

RELATED APPLICATION[0001]This application claims the benefit of priority under 35 U.S.C. §119(e) of U.S. Provisional Application No. 61 / 441,248, filed Feb. 9, 2011, and U.S. Provisional Application No. 61 / 474,739, filed Apr. 12, 2011, both of which are incorporated herein by reference in their entirety.TECHNICAL FIELD[0002]Aspects of the present disclosure relate to detection, monitoring and / or analysis of cerebro-hemodynamic conditions, such as the existence of or change in arterial occlusion.BACKGROUND[0003]A number of cerebro-hemodynamic characteristics may be clinically useful for diagnosing strokes, trauma, and other conditions that can affect the functioning of the cerebrovascular system. These characteristics may include cerebral blood volume, cerebral blood flow, cerebral perfusion pressure, mean transit time, time to peak, intracranial pressure, and others. Conventional methods for detecting or monitoring these parameters may include physically inserting a probe into the ce...
