Hemodynamic map with isolines of total contractility plotted. The ideal normohemodynamic state of MAPideal = 85 Torr and SIideal = 47 ml/m2 is also shared with the ideal value of contractility LSWIideal = 52.8 g.m/m2, marked as 0% deviation in contractility from ideal. Other isolines of contractility plotted are: LSWI = 39.3 (passing through ideal value of normotension MAPideal = 85 and low end of normody-namic flow SI = 35), marked -34.3%, i.e., 34.3% hypocontractility; LSWI = 26.4 => -100%, i.e., 100% hypocontractility; LSWI = 73.0 => +38.2%, i.e., 38.2% hypercon-tractility; and LSWI = 105.5 => +100%, i.e., 100% hypercontractility
