ABSTRACT:
A method and apparatus for ventilator pressure and optimization administers fixed stepwise pressure changes to the lungs of a patient and measures the lung volume change resulting from each pressure change. Critical opening pressure, critical closing pressure, and overdistention pressure are determined by changes in lung volume corresponding to the fixed stepwise pressure changes.
