1. A respiratory therapy and monitoring method comprising:

  • providing a first conduit having a proximal end, a distal end, and a first lumen defined, therethrough from the proximal end to the distal end;

    delivering, via the first conduit, a flow of gas from a gas supply to an airway of a user over a plurality of respiratory cycles;

    monitoring a gas flow characteristic using a pressure sensor, a flow sensor, or both operatively coupled to the airway of the user while the flow of gas is passing through the conduit;

    accounting for an offset in the gas flow characteristic caused by the flow of gas; and

    determining at least one respiratory variable of such a user based on the gas flow characteristic and the accounting for the offset.
