The Model of the Respiratory System as an Educational Device for Simulation of the Ventilatory Parameters Effect Upon the Intrapulmonary Conditionsull


The aim of the work was to design a simulator of the human respiratory system consuming oxygen and producing carbon dioxide. The respiratory quotient, tidal volume, mechanical parameters of the systemand other parameters should be similar to the physiological ones, so that the simulator could be used for simulation of artificial ventilation of a real patient. The model consists of a high-volume plastic box assuring the desired lung compliance, a propane-butane burner equipped with a water-based cooling system, oxygen and CO2 analyzers of the “intrapulmonary” gases and a control system. The simulator is an educational device suitable for testing of the infl uence of the ventilatory parameters upon the intrapulmonary conditions similarly as during artificial lung ventilation of a human patient.
