attitude of utandningstid at the artificial respiration based on a deviation from a stable condition of the final concentrations of tidal gas

摘要

A method of setting expiratory time in controlled mechanical ventilation varies a subject's expiratory times; determines end tidal gas concentrations associated with the expiratory times; establishes a stable condition of the gas concentrations; and determines an optimal expiratory time based on a deviation from the stable condition. A device for use in controlled mechanical ventilation comprises means for the same.
