Abstract
A method () for estimating patient airway flow in a non-invasive ventilator system includes: (i) determining () an estimated gas flow; (ii) determining () a proximal pressure error value; (iii) compensating () for the determined proximal pressure estimate error value; (iv) compensating () for an error in the estimated gas flow; (v) determining () an estimated gas flow leak; (vi) monitoring () on a breath to breath basis for a leak; (vii) determining () a gas flow leak factor; (viii) adjusting () the estimated gas flow leak; (ix) detecting () a bias on the airway flow estimate; (x) determining () that the system is within a quiescent state of a breath; (xi) de -biasing () the estimated gas flow to drive the bias to near zero; and (xii) suspending () breath to breath bias correction on an immediately subsequent breath.
