Impact of oscillatory parameters on gas transport in bifurcation geometries

High-frequency ventilation (HFV) is a medical ventilation method which uses fast, shallow inflations. The small tidal volume per inflation means gas transport does not occur via emptying and refilling the lungs, and so how to optimise this transport is still not understood. This thesis investigates the relationship between oscillatory parameters and gas transport during high-frequency ventilation. This thesis reports gas transport can be maintained at higher frequencies than the frequencies currently utilised in clinics, thereby, minimising ventilator-induced lung injuries.
