1. A method for respiratory support, the method comprising:

  • measuring a pressure;

    measuring an inlet flow and an outlet flow;

    based on the inlet flow and the outlet flow, calculating a net flow;

    predicting patient effort based at least in part on a relationship between a first value related to the measured pressure, a second value related to the net flow, and a third value related to patient effort; and

    updating an interim value based at least in part on the prediction of the patient effort, wherein the interim value does not directly correspond to a respiratory parameter.
