CA 2730636

In some embodiments, systems and methods for identi-fying 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 per-fusio condition. If such a condition is detected, an event may be trig-gered, such as an alert or notification.

Linvention concerne, dans certains modes de réalisation, des systèmes et des procédés didentification dun état de faible irrigation par transformation dun signal à laide dune transformation par ondelettes, pour générer un scalogramme. Une bande de pulsations et des régions de marqueur adjacentes sont identifiées dans le scalogramme. Les caractéristiques des régions de marqueur sont utilisées pour détecter lexistence dun état de faible irrigation. Si un tel état est détecté, un événement tel quune alerte ou une notification peut être déclenché.
