Optimal pulmonary arterial blood pressure.
Based on the principle of minimum power, a mathematical model of the functional state of the pulmonary circulatory and respiratory systems is presented. The optimization model minimizes the power expended by the right heart and respiratory muscles. The pulmonary diffusing capacity control mechanism is considered. Mean pulmonary arterial blood pressure and ventilation are determined depending on oxygen transport parameters for man under normal and chronic pathological conditions. Theoretical results are compared with clinical data.
