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).
