Neonatal Chest Compression DeviceCourtney GallagherJillian ZeberAdvisor: Dr. Walsh, Vanderbilt NICU

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.

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.

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.

Solution Proposal• Pneumatic pump device • Possible Modifications

• Electronic pump• Inflatable balloon

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

Factors

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

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

Current Work

• Building initial prototype

• Meeting with Isabelle scheduled for next week• Measure chest compliance and required force• Test initial prototype

Future Work• After testing, make modifications and re-test

• Research possibility of electric pump

• Design Safe

• Make Demo

• Evaluate effectiveness against traditional method

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