Selecting ventilator settings using INVENT: a system including physiological models and penalty functions

This paper describes INVENT, a system for selecting ventilator setting based on physiological models and penalty functions. The models and penalty functions included in INVENT are first described followed by an example of the use of the system in selecting ventilator settings for a patient residing in the intensive care unit. For this patient, the advice given by the system is shown to be reasonable and consistent with clinical opinion.
