1. A method of determining a mask leak conductance in a patient respiratory device, comprising:
calculating, with filtered measures of flow and pressure, a first estimate of leak conductance which responds relatively quickly to changes in leak conductance,
calculating, with the filtered measures of flow and pressure, a second estimate of leak conductance which responds more slowly to changes in leak conductance, and
determining the mask leak conductance as a function of the first and second estimates of leak conductance.
