METHOD AND APPARATUS FOR DETECTING AND QUANTIFYING INTRINSIC POSITIVE END-EXPIRATORY PRESSURE

摘要

The present invention describes a method and apparatus for detecting and quantifying intrinsic positive end-expiratory pressure (PEEPi) of a respiratory patient breathing with the assistance of a ventilator. A processing device receives respiratory airway data from one or more sensors adapted to non-invasively monitor a respiratory patient, calculates from the respiratory airway data two or more parameters that are indicative of or quantify intrinsic positive end-expiratory pressure of the patient, and generates an indication intrinsic positive end-expiratory pressure (PEEPi).

1. A method for detecting and quantifying intrinsic positive end-expiratory pressure (PEEPi) of a respiratory patient breathing with the assistance of a ventilator comprising:
receiving by a processing device respiratory airway data from one or more sensors adapted to non-invasively monitor a respiratory patient; correcting for leaks in an airway circuit of the ventilator by the processing device by modifying the respiratory airway data to compensate for leak flow in the respiratory airway data; calculating from the modified respiratory airway data by the processing device two or more parameters that are indicative of or quantify intrinsic positive end-expiratory pressure of the patient; and generating by the processing device an indication of intrinsic positive end-expiratory pressure based on the two or more parameters.
