The Division of Pediatric Critical Care Medicine is engaged in a wide range of clinical, translational, and basic science research spanning a number of diverse topics. Specific areas of research interest include respiratory mechanics to optimize mechanical ventilation; mechanisms of inflammatory and oxidant-mediated lung injury; extracorporeal membrane oxygenation (ECMO) and ventricular assist devices (VAD); the pharmacokinetics, pharmacodynamics and safety profiles of understudied medications; and using various methodologies to improve education, hand-offs, communication, and overall patient safety.
