Daniel Ouellette, MD, FCCP, comments: We have learned that patients with ARDS should be treated with mechanical ventilation in a fashion that minimizes driving pressure and optimizes PEEP. The use of electrical impedence tomography to noninvasively inform clinicians about optimal PEEP in ARDS patients receiving extracorporeal membrane oxygenation is therefore intriguing. Conclusions are limited by the small size of this study. Further work will be needed to learn if these measurements will be generally applicable.
