Although maintaining some amount of positive end-expiratory pressure (PEEP) seems essential, selecting and titrating a specific level for patients with ARDS remains challenging despite extensive research on the subject. Although an "open lung" approach to ventilation is popular and has some degree of biological plausibility, it is not without risk. ⋯ Here we present a pragmatic approach based on simple measurements available on all ventilators, focused on achieving balance between the potential risks and benefits of PEEP. Acknowledging "best PEEP" as an impossible goal, we aim for a straightforward method to achieve "better PEEP."
