Conditions characterized by a fall in cardiac output are associated with alterations in cardiopulmonary variables and activation of cardiovascular and respiratory control mechanisms. In order to study these complex relationships, we developed a comprehensive cardiopulmonary model consisting of a circulation, a respiration and a metabolism block. In this work, the model is used to simulate cardiovascular dynamics in pathological conditions with an acute decrease in heart function. In particular, two conditions are examined: the first is characterized by a decrease in heart contractility, simulated in the model via a reduction in the left ventricular end-systolic elastance. The second consists in an increase in pulmonary arterial resistance, associated with pulmonary embolism. In conclusion, the proposed model may be of value in clinical settings to illustrate the complex relationship among cardiovascular variables.

Abstract

Conditions characterized by a fall in cardiac output are associated with alterations in cardiopulmonary variables and activation of cardiovascular and respiratory control mechanisms. In order to study these complex relationships, we developed a comprehensive cardiopulmonary model consisting of a circulation, a respiration and a metabolism block. In this work, the model is used to simulate cardiovascular dynamics in pathological conditions with an acute decrease in heart function. In particular, two conditions are examined: the first is characterized by a decrease in heart contractility, simulated in the model via a reduction in the left ventricular end-systolic elastance. The second consists in an increase in pulmonary arterial resistance, associated with pulmonary embolism. In conclusion, the proposed model may be of value in clinical settings to illustrate the complex relationship among cardiovascular variables.
