transpulmonary pressure

Physiology The difference between airway pressure and pleural pressure–P_AW—P_PL, a clinically important respiratory measure in ICU Pts; it is also derived by multiplying the airway pressure by the ratio of lung parenchyma elastance and total lung elastance; for a given P_AW, rise of the P_PL has effects on hemodynamics, lung distention and recruitment, and interstitial lung fluid–pulmonary edema
