Abstract

Eine von uns entwickelte Methode zur Bestimmung der Compliance der Arteria pulmonalis (Cp a) wird dargestellt. Aus der Höhe der systolischen Welle in der dZ-Kurve des Impedanz-Pulmonal-Rheogramms und aus der Druckamplitude der Arteria pulmonalis kann man Cp a berechnen: Cp a =H/dP x 124,37+2,56 (ml/mm Hg).

Bei “Beine hoch” und unter Belastung fällt Cp a ab, weil der Anstieg des Schlagvolumens dabei zur Vergrößerung des dP führt. Bei Patienten mit pulmonaler Hypertonie vergrößert sich dp und vermindert sich H infolge der Erhöhung des Lungengefäßwiderstandes und von Pp a; dadurch nimmt Cp a ab.
