MECHANICAL VENTILATION SYSTEM FOR RESPIRATION WITH DECISION SUPPORT

摘要

The invention relates to a mechanical ventilation system for respiration of a patient, the system being adapted for providing decision support for mechanical ventilation. Control means is adapted for using both first data and second data, indicative of the respiratory feedback in the blood, in physiological models (MOD) descriptive of, at least, lung mechanics, and/or gas exchange in the lungs of the patient, the physiological models comprising a number of model parameters (MOD_P). The control means is further arranged for simulating the effect on one, or more, model parameters (MOD_P) of the physiological models for a suggested value of the positive end expiratory pressure (PEEP) setting for the ventilation means, and thereby provide decision support in relation to said suggested PEEP value. The invention is advantageous for providing mathematical based models of changes in physiology in response to changes in ventilator settings of the PEEP thereby allowing mathematical physiological models to predict changes in clinical variables for a given value of PEEP.
