title: Mathematical model of jet ventilation.
abstract: The design of jet ventilators has always been empirical because no theory linked jet geometry, driving pressure, gas density and lung mechanics. A mathematical means has been developed linking these parameters to model jet ventilation. The mathematical model predicts the flow into a physical lung model, but under-estimates flow into the lungs when used to predict the effects of jet ventilation on an animal model at high rates of ventilation. This is attributed to a reduction in compliance with increasing ventilatory frequency.
