Extensive Research Description

I plan to devote my academic clinical research career to applying new, noninvasive technologies to the clinical problems seen acutely in children by designing and executing carefully planned patient-oriented research. During the past several years I have been able to successfully complete several research projects using new technologies in the pediatric emergency department such as capnography and portable spirometry. Furthermore, I have been able to document that capnography is not being utilized to its full potential in both the emergency and critical care settings. My goal is to continue patient oriented research using noninvasive technologies that provide us with objective patient assessment and can be used to make timely clinical decisions, improve patient safety and reduce medical costs.

  • Can end-tidal carbon dioxide monitoring reduce the frequency of hypoxia during moderate sedation with ketamine in children?
  • Identifying the barriers and facilitators to the implementation of new technology in acute care areas
  • A qualitative study regarding providers perceptions on capnography use during moderate sedation
  • Evaluating trainees' ability to normally ventilate children via bag-valve mask ventilation through capnography
  • Assessing the use of capnography during critical events in the Emergency Department

I have also been involved in medical education research. Along with the fellowship directors in pediatric emergency medicine across the country, we worked to map out Entrustable Professional Activities for our specialty. We are now evaluating our fellow Milestones, clinical work hours, and levels of autonomy.
