S01E41: EIT-Guided PEEP in ARDS — Precision Ventilation or Too Much Titration?

In this episode of PRISM Rounds, we discuss the 2026 AJRCCM EITVent randomized clinical trial and its accompanying editorial. The study asked whether electrical impedance tomography, or EIT, could help clinicians individualize PEEP in adults with moderate to severe ARDS compared with the traditional lower PEEP/FIO2 table.The overall trial was neutral: EIT-guided PEEP did not reduce 28-day mortality, ventilator-free days, length of stay, or major safety outcomes. But an important subgroup signal emerged in patients with higher lung recruitability, raising a practical bedside question: should EIT be used selectively to guide precision ventilation rather than as routine daily exhaustive PEEP titration?We discuss the trial design, the “collapse-overdistension crossing point,” the editorial’s caution about repeated recruitment maneuvers and decremental PEEP trials, and how this should influence bedside ventilator thinking in ARDS.Educational only.
