Compositional and geometric unifying approach for modeling the mechanical ventilator-Human respiratory system

Abstract

The objective of this research work is to present the Port Hamiltonian modelling of integrated Port Hamiltonian model of the mechanical ventilator- human respiratory system. Three case scenarios which include a healthy person, a sedated patient, and a spontaneously breathing patient are used to demonstrate the application of this model. The proposed model is sufficiently detailed enough to reproduce human respiratory responses to be applied in different representations of positive pressure while still maintaining low computational costs. The simulated results obtained are comparable to those in literature. The presented formulation of the Port Hamiltonian lumped parameter model can be applied in the design of robust controllers for Mechanical ventilators' patient dynamics.
