a theoretical analysis of the step response in the closed cardiovascular system induced by a sudden shift of the right cardiac output curve predicted that if the relations of the right heart output ( cor ) and the total systemic capillary flow ( cfs ) to the systemic venous pressure ( psv ) are linear , then the time course of psv change will become monoexponential with a time constant t given by t = csv/ ( gr + gs ) , where csv is the systemic vein compliance and gr and gs are the conductances of the transient cor-psv and cfs-psv relationships .
