  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. 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.

  4. 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, 2 to 3 cm. • Apply the 11-12 lbs of force directly below the nipples in the center of the chest. • Verified with bathroom scale and free weights. • Maintain a rate of 80-100 compressions per minute for blood pumping. • Simple and easy to use by Dr. Walsh in the NICU

  5. Solution Proposal • Possible Modifications • Inflatable balloon • Backboard • Pneumatic air cylinder • Air compressor

  6. Device Components • Pneumatic cylinder, air compressor, solenoid valve, and a automatic controller • Use 1.1 inch diameter plunger to displace chest 2-3 cm. • 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 • Wheel-up cart supporting base structure and air compressor

  7. Factors • Provide necessary but not excessive force (11-12 lbs = 5 kg) • Materials that can be sterilized • Comfortable • Quick setup • Potentially portable • Safety • Adjustable

  8. 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 cylinder • Purchased materials to build initial prototype • Pneumatic cylinder and Air compressor • Measured force required to provide chest compressions

  9. Current Work • Acquiring needed materials • Building initial prototype • Testing basic setup on Isabel

  10. Future Work • After testing, make modifications and re-test • Research solenoid valve and controllers • Pre-set timers (automatic) • Foot pedal w/ exhaust (manual) • Design Safe • Make Demo • Evaluate effectiveness against traditional method

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