METHOD AND APPARATUS FOR MEASURING AND/OR DETECTING FLOW BEHAVIOR OF A BODY FLUID USING ULTRASOUND

Document Type and Number:

WIPO Patent Application WO2006030354

Kind Code:

A9

Abstract:

An ultrasound method and apparatus for detecting and/or measuring the pulse and/or blood flow of a subject calculates a Doppler signal spectrum from an ultrasound signal backscattered from the blood in an artery of the subject. Indicia of flow behavior are calculated for several frequency slices within the Doppler signal spectrum and these indicia may be used to determine pulsatility and/or blood flow, as well as other parameters of flow behavior. Because of the robust nature of the calculated indicia, the ultrasound method and apparatus has particular use in an Automated or Semi-Automated External Defibrillator (AED) for determining whether to defibrillate a patient.
