摘要：
A hemodynamic monitoring instrument includes a processor and an output device. The processor (30) is arranged to receive a physiological parameter indicative of heart rate and a physiological parameter indicative of arterial blood pressure and is configured to compute (50) a hemodynamic parameter correlating with systemic vascular resistance (SVR) based on the received physiological parameter indicative of heart rate and the received physiological parameter indicative of arterial blood pressure. The output device includes least one of: (i) a display (24) configured to display the computed hemodynamic parameter; and (ii) an alarm (32, 34) configured to generate a perceptible signal responsive to the computed hemodynamic parameter satisfying an alarm criterion (52). The processor in some embodiments computes the hemodynamic parameter using a fuzzy membership function representing the heuristic ‘quantitative ABP measure is low AND quantitative HR measure is slightly high or high’ OR ‘quantitative ABP measure is very low’.
