Low perfusion signal processing systems and methods

摘要

In some embodiments, systems and methods for identifying a low perfusion condition are provided by transforming a signal using a wavelet transform to generate a scalogram. A pulse band and adjacent marker regions in the scalogram are identified. Characteristics of the marker regions are used to detect the existence of a lower perfusio condition. If such a condition is detected, an event may be triggered, such as an alert or notification.
