METHOD AND APPARATUS FOR PRESENTING INFORMATION CONCERNING FLOW BEHAVIOR OF A BODY FLUID EXTERNALLY MEASURED BY ULTRASOUND

摘要

A flow behavior monitor for presenting ultrasound measurements of an indicia of flow behavior of a fluid in a subject. The indicia of flow behavior are calculated for several frequency slices within a Doppler signal power 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 flow behavior monitor has particular use in an Automated or Semi-Automated External Defibrillator (AED) for determining whether to defibrillate a patient.
