Clinical review: What are the best hemodynamic targets for noncardiac surgical patients?

Table 1 Goals of therapy, monitors and main outcomes

Variable	Monitor	Reported clinical effects [references]
Dynamic indices of fluid responsiveness
Corrected flow time	TED	Decrease LOS or complications [22, 24, 28], increase LOS [61, 62]
Stroke volume	TED, Vigileo FloTracsystem™, LiDCOrapid™	Decrease LOS or complications [23–28]
Pulse pressure variation	Multiparametric monitor, LiDCOrapid™	Decrease LOS and complications [30]
Plethysmography variability index	Plethysmography	None [31]
Stroke volume variation	Vigileo/FloTracsystem™, LiDCOrapid™	Decrease LOS and complications [32]
Systolic pressure variation	PiCCOplus™	None [33]
Flow indices
Oxygen delivery	PAC, LiDCOplus™, Vigileo/FloTracsystem™	Decrease mortality [35–38], decrease complications [35–38, 64, 65, 68], none [66]
Cardiac index	PAC	Decrease complications [39], none [40–43]
Indices of adequacy of perfusion
Venous oxygen saturation	PAC	None [52]
Oxygen extraction ratio	Blood gas	Decrease complications [53]
