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.

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 Pneumatic pump device Possible Modifications Electronic pump Inflatable balloon

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
