Figure 5: Figure 5 shows the relation between estimated PLVEDtm (PLVED PLVED) and PLVEDtm over the range of filling pressures and PEEPs. Volume loading increased and PEEP decreased both estimated PLVEDtm (PLVED PRVED) and PLVEDtm. PLVED, left atrial end-diastolic pressure (mmHg); PRVED, right ventricular end-diastolic pressure (mmHg).
