3. Goal
To Design a device using High-Frequency Oscillation that can be used to ventilate a neonatal through pediatric patient in an emergency situation without regard to user interaction or environmental situation

4. Timeline

5. Our Criteria Delivers sufficient O2 to infant
Does not cause harm to either patient or caregiver
Is portable
Accommodates patients ranging from neonatal to small child
Requires no attention after being setup for use
Meets ISO standards

6. 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

7. 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)

8. What is HFO?
HFO employs a mechanical oscillating device which forces small impulses of gas both into and out of the airway. This causes the gas in the airway to oscillate in a sinusoidal pattern.

9. Why HFO?
No continual swings in pressure between PEEP (positive end expiratory pressure) and CPAP (continuous positive airway pressure)
Ability to maintain open alveoli
May reduce barotrauma because of less distention in the lungs
Ability to facilitate the upward movement of the mucociliary blanket
