The chart shows the Frank-Starling effect of Intravascular Volume (horizontal axis), Inotropy (parameter) on Ejection Phase Contractility (vertical axis). Three Frank-Starling curves are shown with three levels of inotropic state. A patient who is normovolemic and normoinotropic exhibits a normal level of ejection phase contractility. However, the same level of contractility can be achieved in a hypovolemic patient who is administered positive inotropes, or in a hypervolemic patient with negative inotropes administration.
