We propose that complex (nonlinear) fluctuations of hemodynamic variables including systemic blood pressure parameters) during cardiovascular surgery contain information relevant to risk assessment and intraoperative management. Preliminary analysis of a pilot study supports the feasibility and potential merits of performing a larger, prospective study to assess the clinical utility of such new dynamical measures and to evaluate their potential role in enhancing
contemporary approaches to risk assessment of major adverse events.
