Figure 8. — Cardiovascular response to step changes in the level of positive end-expiratory pressure (PEEP) of a virtual patient with either pulmonary ARDS (ARDS, black squares) or extra-pulmonary ARDS (ARDS, gray circles). Each PEEP level is applied for a period of 20 minutes and simulation results are averaged over the last 10 minutes of each PEEP segment. LV, left ventricular; RV, right ventricular; , stroke volume index; , end-diastolic volume index; , end-systolic volume index.
