Sensitivity analysis of a simple cardiorespiratory model in postoperative cardiac patients

This paper investigates the influence of four parameters of a simple cardiorespiratory model on relevant physiological variables, such as cardiac output, CO, and oxygen utilization coefficient, CU. In particular, analysis of the sensitivity of these variables to changes on cardiac contractility, CC, blood volume, BV, hemoglobin, Hb, and dead space volume, DS, is described. With this analysis, information is obtained about which parameters are more critical and require particular attention in evaluating the cardiopulmonary performance of postoperative cardiac patients.
