device for adjustment of the required mechanical ventileringsparametrar based on patientfysiologi

摘要

A method of setting a subject's breath size in controlled mechanical ventilation, comprising varying a subject's tidal volumes and/or inspiratory pressures for a predetermined inspiratory time and predetermined expiratory time; determining end tidal gas concentrations associated with said tidal volumes and/or inspiratory pressures; and curve-fitting a relationship between said tidal volumes and/or inspiratory pressures and said end tidal gas concentrations.
