In this paper, we have applied and compared two scenarios: 1) The linear pressure (ramp amplitude) for the whole cycle without any optimization of the lung pressure at different respiratory states (named without optimization) and 2) Optimized lung pressure and diaphragm force using an automatic tuning algorithm based on inverse FE analysis methodology during a whole respiratory cycle and at different states (with optimization).
