Abstract
The disclosed concept maintains that Q=Q−Q, where, Qis the estimated patient flow, Qis the estimated leak and Qis the measured total circuit flow. Qis given by a transfer function φ(χ) where x is a set of independent measured or fixed variables. The transfer function is thus Q=φ(χ). The transfer function (φ(χ) is adjusted given the constraint that, Qshall be zero. The transfer function converges over time to accurately estimate the leak because over an extended time the mean patient flow will always be zero. In one example, φ(χ)=gPand the coefficient gis adapted until Qis zero.
