  1. Child Defibrillation By Todd Braithwaite

  2. Introduction Modern Medicine has not yet created protocols for successfully defibrillating children under twelve years old. There is a lack of research on how electrical currents affect the anatomy and physiology of a child’s body. Adequate research on this subject could improve the outcomes of advanced lifesaving (ALS) measures for children.

  3. Goals - First • Demonstrate effects of body size on current distributions in body • Expect to find dangerous levels in child body with adult shock • Publish findings

  4. Goals - Second • Redesign defibrillator for child body size • Expect to change strength & duration of shock • Publish findings

  5. Cardiac Defibrillation - Basics • Heart controlled by electrical signals • Fibrillation - rapid & irregular beating of the heart • Electrical shock used to restore regular heart beat (defibrillation)

  6. Defibrillation Basics - cont’d • Paddles (electrodes) placed on body • Electrical shock applied • View results • Repeat if necessary Note Too big of a shock will permanently damage the body tissue

  7. Defibrillator • Lifepak 500 Automated External Defibrillator http://www.lifesaving.com/catalog/emsresus.htm

  8. Electrodes

  9. Usage of Defibrillator • Location of Electrodes

  10. My Project • Model current distribution in body • Finite Difference Frequency Domain (FDFD) Modeling • Written in MATLAB

  11. Model of Human Body • No model of child body • Adult body model • Scale to child size

  12. MATLAB • FDFD code written in house • Successive Over Relaxation (SOR) method • Resolution (matrix size) determined by computing power available

  13. MATLAB -cont’d • Results compared against published current patterns

  14. Project Timeline • Working FDFD code - May 1, 2000 • Human model - May 28, 2000 • Preliminary results - June 27, 2000 • Simulations completed - July 30, 2000 • Write up completed - August 15, 2000

  15. Close • Defibrillators designed for adults • Lack of research on defibrillating children • Future design changes in defibrillators

  16. Resources • Dr. Furse • Articles - 2 so far • Web sites - none yet
