Abstract
A method for estimating patient airway flow in a non-invasive ventilator system. The method includes the steps of (i) determining an estimated gas flow at the proximal end of the tubing; (ii) determining a proximal pressure error value by subtracting the measured pressure at the proximal end of the tubing from the estimated pressure at the proximal end of the tubing; (iii) compensating for the determined proximal pressure estimate error value; (iv) compensating for an error in the estimated gas flow at the proximal end of the tubing by feeding the estimate back into a sum of accumulated flows; (v) determining an estimated gas flow leak; (vi) monitoring for a leak in the non-invasive ventilator system; (vii) determining a gas flow leak factor; (viii) adjusting the estimated gas flow leak; and (ix) compensating for bias in the patient airway flow.
