Abstract

Verfahren zum automatisierten Bestimmen von hämodynamischen Parametern in einem Blutgefäß an invasiv aufgezeichneten Pulswellen durch eine Analyse dieser Pulswellen und/oder von aus der Gesamtheit ausgewählten Pulswellen, mindestens jedoch einer Pulswelle, durch ein Aufzeichnen eines zeitlichen Druckverlaufs in einem Blutgefäß an nur einem einzigen Messpunkt in dem Blutgefäß, wobei der dabei aufgezeichnete Druckverlauf nachfolgend einer automatisierten Signalverarbeitung zugeführt wird, wobei an einem vorher bis zu dem vorgesehenen Messpunkt innerhalb des Blutgefäßes eingeführten Druckmesskatheter (1) mit einem Druckmesssensor (2) folgende Verfahrensschritte ausgeführt werden: - Aufzeichnen und Speichern des zeitlichen Druckverlaufs und Erfassen mindestens eines Pulswellensignals (PW) an dem Messpunkt, - Extrahieren eines Pulswellenechoanteils (PE) aus dem mindestens einen Pulswellensignal (PW) und Ermitteln eines Zeitversatzes (T) zwischen einem Pulswellengrundsignalanteil (PG) und dem Pulswellenechoanteil (PE) im Pulswellensignal (PW), - Umrechnen des Zeitversatzes (T) in eine Pulswellengeschwindigkeit (PWV) mittels eines gegebenen Referenzabstandes zwischen einer Echostelle des Blutgefäßsystems und der Position des Druckmesssensors (2) im Blutgefäß und/oder - Bestimmung von insbesondere einer Pulswellengeschwindigkeit (PWV) ohne Berücksichtigung eines Referenzabstandes über ein gegebenes Druck/Fluss- Modell und ein Druck/Volumen-Modell des Blutgefäßsystems.
