Dynamic lung elastance ( E drs )-Pressure-PEEP plot. Top Left Panel: Patient 2, Top Right Panel: Patient 6. Both patients show significant E drs drop from lower zero PEEP to PEEP 15cmH 2 O. Further increase of PEEP to 20cmH 2 O shows increase of overall E drs . Bottom Left Panel: Patient 8, Bottom Right Panel: Patient 10. Both patients show a consistent drop in overall E drs with increasing of PEEP and overall E drs did not rise with PEEP for the entire ranged considered.
