Abstract A flow simulator designed to produce well defined pulsatile flows of water through two series-connected compartments is used to simulate either the right or the left side of the heart. The stroke volume and the diastolic volume of one of the compartments can be preset to desired values. In 14 experiments comprising 102 indicator recordings cold 5% dextrose solution and ink, were used as indicators being injected as boli at a defined instant during the pumping cycle by means of a power injector. A data-retrieval procedure based on a mathematical two-compartment model is used to calculate stroke volumes and ventricular volumes using the indicator recordings as input data. The results are compared with the actual volumes and acceptable agreement was obtained in nine experiments.
