The transpulmonary pressure calculated using the elastance approach reflects the pressure in the non-dependent region, whereas the transpulmonary pressure determined using the direct method reflects the pressure in the area adjacent to the esophageal balloon
Ppl directly in the dependent and non-dependent regions in lung-injured pigs (A) and human cadavers (B) and compared the results with those estimated by esophageal pressure. Reprinted with permission of the American Thoracic Society.
