Outline Goal Project Background Timeline Current Status Future Plans Questions

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

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)

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.
