Method and apparatus for optimizing mechanical ventilation

摘要

In order to select an optimal ventilation mode for mechanically ventilating a patient, from among a number of ventilation modes, a mathematical description of the patient's respiratory system is produced in a computer from measured parameters related to properties of the respiratory system, and in the computer the mathematical descriptions for different modes of ventilation are tested on the mathematical description to obtain simulated results. An operator can selected a mode of ventilation to be analyzed by comparing the simulated results with a therapeutic goal, so that an optimal ventilation mode can be selected. Alternatively, the computer can iteratively test a number of modeled ventilation modes to identify the ventilation mode which comes closest to the therapeutic goal.
