Automated Titration of Oxygen Fraction in Inspiratory Mixture in Mechanical Ventilation of Life-size Mannequin

Abstract

Mechanical ventilation is often used in patients suffering inadequate oxygenation. Many ventilator regimens have been already introduced, however mechanical ventilation still causes significant adverse effects. Practicing an intubation and guidance of mechanical ventilation can be crucial for a successful use of mechanical ventilation in the clinical practice. Use of simulators with life-size mannequins represents a unique opportunity to realize simulations with a high fidelity. Aim of this paper is to introduce a scenario prepared for a demonstration of automated ventilatory regimen with automatically controlled fraction of oxygen in a ventilatory mixture with a possibility of studying the effect of ventilatory parameters upon vital signs of the mannequin. The simulator with life-size mannequin and real medical devices used in the simulation increase its fidelity and are used in education of biomedical technicians, biomedical engineers and medical rescuers.
