Modeling and Simulation of Two Patient Single Ventilator Systemwith Simcenter Amesim

In this paper, we propose a simulation model using Simcenter Amesim for the two patient single ventilator setup. The model captures the connections and control of the mechanical components to ensure the proper ventilating function for pressure control mode. Using multiple model simulations with different lung parameter values, we demonstrate that two patients can be safely paired together on one ventilator if their lung compliances are similar. The modeling approach demonstrated herein can be used to quantify the impact of varying different parameters on the overall system performance and to accelerate the development of mechatronic medical devices.
