摘要：A Moving Window Least Squares (MWLS) approach is applied to estimaterespiratory system parameters from measured air flow and pressure. In each window,elastance E(or resistance R) is first estimated, and a Kalman filter may be applied to theestimate. This is input to a second estimator that estimates R (or E), to which a secondKalman filter may be applied. Finally, the estimated Eand Rare used to calculate musclepressure P(t) in the time window. A system comprises a ventilator (), an airway pressuresensor (), and an air flow sensor (), and a respiratory system analyzer () that performs theMWLS estimation. Estimated results may be displayed on a display () of the ventilator orof a patient monitor. The estimated P(t) may be used to reduce patient-ventilatordyssynchrony, or integrated to generate a Work of Breathing (WOB) signal forcontrolling ventilation.
