This work introduces a respiratory simulation system, which is bridging the gap between the complex, real anatomical environment and the safe, cost-effective simulation methods. The presented electro-mechanical lung simulator, xPULM, combines in-silico, ex-vivo and mechanical respiratory approaches by realistically replicating an actively breathing human lung. The reproducibility of sinusoidal breathing simulations with xPULM was verified for selected breathing frequencies (10-18 bpm) and tidal volumes (400-600 ml) physiologically occurring during human breathing at rest. Human lung anatomy was modelled using latex bags and primed porcine lungs. High reproducibility of flow and pressure characteristics was shown by evaluating breathing cycles (nTotal = 3273) with highest standard deviation |3σ| for both, simplified lung equivalents (μV˙ = 23.98 ± 1.04 l/min, μP = -0.78 ± 0.63 hPa) and primed porcine lungs (μV˙ = 18.87 ± 2.49 l/min, μP = -21.13 ± 1.47 hPa). The adaptability of the breathing simulation parameters, coupled with the use of porcine lungs salvaged from a slaughterhouse process, represents an advancement towards anatomically and physiologically realistic modelling of human respiration.}, subject = {Breathing Simulation}, language = {en} } @misc{PastekaForjanDrauschke, author = {Pasteka, Richard and Forjan, Mathias and Drauschke, Andreas}, title = {Comparison of breathing patterns for aerosol inhalation using an electro-mechanical lung simulator}, series = {ALTEX Proceedings - EUSAAT 2018, Linz}, journal = {ALTEX Proceedings - EUSAAT 2018, Linz}, subject = {Biomedical Engineering}, language = {en} } @misc{ForjanPastekaDrauschke, author = {Forjan, Mathias and Pasteka, Richard and Drauschke, Andreas}, title = {Lung simulation - an alterna� tive approach to animal testing for applications in aerosol and respiratory research}, series = {ALTEX Proceedings - EUSAAT 2018, Linz}, journal = {ALTEX Proceedings - EUSAAT 2018, Linz}, subject = {Biomedical Engineering}, language = {en} }
