While initially ventilating a patient with acute respiratory distress syndrome (ARDS),the extrinsic positive end-expiratory pressure (PEEPᴇ)should be maintained using which of the following methods? A) 50% of intrinsic positive end-expiratory pressure (PEEP_I) B) Open lung approach C) Offset intrinsic PEEP D) Minimize mean airway pressure

During the early phase of acute respiratory distress syndrome (ARDS),it is important to keep extrinsic positive end-expiratory pressure (PEEPᴇ)high enough to at least exceed the inflection point on a slow or static pressure volume.It is generally accepted by clinicians that the deflation limb of a slow pressure-volume loop best approximates the end-expiratory pressure range required to prevent alveolar collapse.Maintaining PEEPᴇ above this pressure range helps to prevent opening and closing of small airways and alveoli.This is referred to as the open lung approach to ventilatory management.
