SIMULATIONS OF THE VENTILATION IN INTERACTIONS BETWEEN REAL VENTILATOR AND PHYSICAL MODEL OF THE LUNG

Teoretično izhodišče. Modeli pljuč predstavljajo učinkovito platformo za učenje zaposlenih v enotah intenzivne terapije. Raziskali smo interakcijo med fizičnim modelom in ventilatorjem pljuč. Metodologija. Uporabili smo eksperimentalno metodo dela. Raziskovali smo funkcije računalniškega simulatorja, ki nam ponuja simulacijo obolenj kot so astma, COPB in ARDS. Prav tako smo uporabili fizični model pljuč Imtmedical Smartlung Adult, ki smo ga ventilirali z ventilatorjem Evita XL. Na modelu pljuč smo spreminjali podajnost, upornost ter uhajanje zraka. Rezultati. Pri nastavljanju podajnosti na modelu pljuč nam je ventilator prikazal vrednosti z odstopanji ± 2 ml/mbar. Večja odstopanja so bila prisotna pri nastavljanju upornosti, in sicer pri nastavljeni upornosti 20, 50 in 200 mbar/l/s. Zaključimo lahko, da nam računalniški program nudi osnovne tipe pogostejših bolnikov, pri fizičnem simulatorju pa zaradi omejitve pri nastavljanju podajnosti pljuč ni mogoče vstaviti vrednosti za paciente. Sklep. Sklenemo lahko, da nam ventilator ustrezno izmeri podajnost, ki smo jo nastavili na fizičnemu modelu pljuč. Prav tako sta simulacijski program in model pljuč zelo dobra načina za učenje in delo z bolniki v intenzivnih terapijah.Theoretical starting point: Lung models represent the effective platform for education of staff in the units of intensive care. We researched the interaction between the physical model and lung ventilation. Research methodology: We used an experimental method and investigated the functions of computer simulator, which offers a simulation of breathe disorders such as asthma, COPD and ARDS. We also used Intermedical Smartlung Adult physical lung model, which was vented with Evita Xl ventilator. Lung model had the flexibility, resistance and air leak setting options. Research results: When setting flexibility on the lung model, the ventilator showed the values of ± 2 mL/mbar. Larger deviations were present when we had set resistance to 20, 50 and 200 mbar/l/s. It can be concluded that a computer program provides basic types of frequent patients and that the physical simulation is not possible due to restrictions in lung flexibility settings. Conclusion: We can conclude that the ventilation properly measured flexibility which was set on the physical lung model. The simulation program and lung model are also very good way to learn and work with patients in intensive care
