  1. Auto Bag Jerome H. Santoyo Jessica S. Yeager Advisor: Richard Fries Vanderbilt University Dept. of Biomedical Engineering

  2. Outline • Goal • Project Background • Timeline • Current Status • Future Plans • Questions

  3. Goal • To Design a device that can be used to ventilate a neonatal patient (< 1 year of age) in an emergency situation without regard to user interaction or environmental situation

  4. The Facts... • In 1992-1994, there was an average of 91,155,000 emergency department visits per year. • Of these visits, 10.2% were for children < 3 years of age. • In 1993-1995, the rate of ambulatory care visits among infants under 1 year of age was four times the rate of children 5-14 years of age. (815 vs. 204 visits per 100 children per year)

  5. More Facts… • In 1995, respiratory diseases accounted for 40% of all hospital discharges. • There were 3.7 million live births in the United States, excluding New York in 1992. • In 1992, 22.9% of all these live births received assisted ventilation for some length of time. • Of these births, 34% received assisted ventilation for more that 30 minutes. • In 1992-1994, payments averaged $8.6 billion for pediatric emergency departments per year.

  6. Timeline

  7. Our Criteria • Delivers sufficient O2 to infant • Does not cause harm to either patient or caregiver and is safe • Is portable • Accommodates neonatal patients (< 1 year of age) • Requires minimal attention after being setup for use • Meets ISO standards

  8. Preliminary ISO Standards • Alarm Testing • high-pressure alarms • breathing circuit integrity alarms • power failure alarms • high and low oxygen alarms • Variables which must be displayed • cycling pressure • end-expiratory pressure • delivered concentration of oxygen

  9. What is Currently Available? • Manual Ventilator • Automatic Ventilators • Conventional Mechanical Ventilation (CMV) • High Frequency Oscillation (HFV) -High Frequency Positive Pressure Ventilation (HPPV) -High Frequency Jet Ventilation (HFJV) - High Frequency Oscillation (HFO)
