Manipulation of positive end-expiratory pressure (PEEP) has been shown to improve the outcome in pediatric acute respiratory distress syndrome (PARDS), but the “ideal” PEEP, in which the compliance and oxygenation are maximized, while overdistension and undesirable hemodynamic effects are minimized, is yet to be determined. Also, for a given level of PEEP, transpulmonary pressure (TPP) may vary unpredictably from patient to patient. Patients with high pleural pressure who are on conventional ventilator settings under inflation may cause hypoxemia. In such patients, raising PEEP to maintain a positive TPP might improve aeration and oxygenation without causing overdistension. We report a case of PARDS, who was managed using real-time esophageal pressure monitoring using the AVEA ventilator and thereby adjusting PEEP to maintain the positive TPP.
