WebBasic Physics of Mechanical Ventilation: A ventilator is just a sophisticated leaf blower. - It is essentially a FLOW DELIVERY MECHANISM. - Inside, there is a precisely controlled turbine. It spins and generates a flow. The CONTROL variables: -FLOW -VOLUME -PRESSURE Compliance A ventilator can be set to “control” one of these variables. WebMay 25, 2024 · Governing Equations. Several governing equations are applied for the numerical analysis of fluid flow and particle motion inside the human airways. Governing equations are also applied at the important sections of the control volume to represent the boundary conditions in different sections (Schreck and Mockros, 1970; Chen, 2002).
