Why Is Peep So High In ARDS?

Why Is Peep So High In ARDS? The rationale for the application of PEEP during mechanical ventilation of the lungs of patients with ARDS is to prevent alveolar collapse, reducing injurious alveolar shear stresses and improving ventilation–perfusion matching, and thus, arterial oxygenation. Why is PEEP increased? Applying PEEP increases alveolar pressure and alveolar volume. The
