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 , 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 , 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 , payments averaged $8.6 billion for pediatric emergency departments per year.
