Abstract

A novel hybrid model combining lumped and distributed parameters has been developed to explore how pulmonary hemorrhage af ects lung mechanics. Drawing on the principles of an electrical circuit analogy, the model integrates resistors and capacitors to represent lung dynamics. Built on a Simulink-based framework, it features user-selectable parameters and an intuitive graphical interface, enabling the simulation of pathological conditions with an emphasis on pulmonary hemorrhage. The study specifically examines variations in lung compliance by modeling the pulmonary system’s response to pressure-controlled ventilation. Findings reveal that even slight changes in compliance can markedly impact air volume, underscoring the potential risks to patients with pulmonary hemorrhage. These results highlight the critical need for precise ventilator adjustments to mitigate adverse outcomes. This innovative use of the Windkessel model not only aligns closely with experimental data but also provides valuable insights into pulmonary ventilation mechanics, of ering a robust tool for managing respiratory and cardiac pathologies.
