Mathematical Simulation of Pulmonary Haemorrhage Cardiovascular Model
Authors
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.
