  1. Neonatal Chest Compression Device Courtney Gallagher Jillian Zeber Advisor: Dr. Walsh, Vanderbilt NICU

  2. Problem Statement • When performed in conjunction with operations of the neck and lower abdomen, there is limited space for manual chest compressions. • Manual chest compressions require both hands to be wrapped around the chest. • 2 occurrences at the Vanderbilt NICU this past year.

  3. Chest Compression Demo • http://www.youtube.com/watch?v=6nS7iPubiEE

  4. Project Goal • Small, easy to setup device that will perform automatic chest compressions on a 0-30 day old infant for use in the OR during a simultaneous procedure.

  5. Performance Criteria • Small but adjustable to fit the size of the baby. • Provide enough force for sufficient chest compressions to reduce the width to one third. • Apply the force directly below the nipples in the center of the chest. • Maintain a rate of 80-100 compressions per minute for blood pumping.

  6. Solution Proposal • Possible Modifications • Electronic pump • Inflatable balloon • Pneumatic pump device

  7. Device Components • Pipes, tubes, and a bulb pump (potential for improvement) • An adjustable elastic Velcro band • To fit different sized infants • A rigid backboard • To concentrate the force on the sternum and not around the entire torso

  8. Factors • Provide necessary but not excessive force • Materials that can be sterilized • Comfortable • Quick setup • Potentially portable • Safety • Adjustable

  9. Previous Work • Researched existing adult compression devices • AutoPulse, Lucas, Thumper • Established goals and criteria that must be met • Discussed with advisors • Decided on a prototype design • Pneumatic device • Purchased materials to build initial prototype

  10. Current Work • Building initial prototype • Meeting with Isabelle scheduled for next week • Measure chest compliance and required force • Test initial prototype

  11. Future Work • After testing, make modifications and re-test • Research possibility of electric pump • Design Safe • Make Demo • Evaluate effectiveness against traditional method

  12. Evaluation • Isabelle in the NICU Simulation Lab • Responds like an alive baby • Provides vitals • Can determine if chest compression are adequate
