Modelling and Simulation of the Pediatric Respiratory System with Endotracheal Tube During Pressure-Controlled Ventilation

Abstract

Incorporating nonlinear ETT resistance into respiratory system models improves prediction accuracy under PCV, particularly in pediatric patients with smaller airways. The findings emphasize the importance of ETT size in ventilator parameter adjustment to optimize ventilation efficiency and minimize lung injury. The validated model provides a useful clinical tool for predicting ETT-related effects and guiding safer ventilation strategies in pediatric intensive care.
