    Abstract: A method of estimating leak flow in a gas delivery system is provided that includes determining an average total flow Qtot (or summation or integral of total flow) of the gas delivery system for each of N breaths, determining Pγ1 and Pγ2 for each of the N breaths, wherein P is a leak pressure of the gas delivery system, γ1 is a first predetermined value, γ2 is a second predetermined value, and Pγ1 and Pγ2 are averages for the breath (summation or integrals may also be used), setting up a system of N equations, one for each of the N breaths, wherein each of the equations has the form Qtot=Gorf.Pγ1+Gvg.Pγ2 and uses the determined Qtot, Pγ1 and Pγ2 for the associated breath, solving the system of N equations for Gorf and Gvg, and using Gorf and Gvg to calculate instantaneous leak Qleak using Qleak=Gorf.Pγ1+Gvg.Pγ2

    Abstract: A system and method for delivering a flow of gas to an airway of a patient (54). The system includes a gas flow generator (52) and a patient circuit (56) comprising a conduit (100) that communicates the flow of gas to a patient. A sensor (62) is configured to measure a rate of the flow gas and generate flow signals based on the measured rate of flow. A controller (64) is operatively connected with the gas flow generator (52) and the sensor (62) and is configured to control a pressure of the flow of gas provided to the patient. The controller (64) receives the flow signals from the sensor (62), determines a rate of change in the flow of the gas, and modifies or compensates the pressure of the flow of gas provided to the patient if the rate of change in the flow of gas provided to the patient exceeds a threshold amount.
