Patent ID: 8544466

Claim:
A method for detecting and quantifying intrinsic positive end-expiratory pressure (PEEPi) of a respiratory patient spontaneously breathing with the assistance of a ventilator without implementing additional invasive or intervening maneuvers on the respiratory patient or on the ventilator, comprising: receiving by a processing device respiratory airway data from one or more sensors adapted to non-invasively monitor an airway of a respiratory patient during spontaneous breathing with the assistance of a ventilator absent airway occlusion; calculating from the respiratory airway data by the processing device two or more PEEPi markers that are selected from a set of PEEPi markers predetermined to be indicative of or quantify intrinsic positive end-expiratory pressure of the patient; and generating by the processing device using a mathematical model a predicted quantitative value representing a magnitude of the intrinsic positive end-expiratory pressure based on a combination of the two or more PEEPi markers, wherein the processing device generates the predicted quantitative value without the respiratory patient or the ventilator undergoing additional invasive or intervening maneuvers to measure PEEPi.
