1. A method of providing oxygen enriched gas to a user of an oxygen concentrator, comprising:

  • measuring the time between a plurality of successive breaths, wherein a breath is determined to begin when a drop in pressure is measured using a pressure sensor coupled to an outlet of a conduit coupling the user to an oxygen enriched gas source;

    determining an average breathing rate based on the time between each of the successive breaths, wherein the time between the penultimate breath and the last breath is not used to determine the average breathing rate; and

    setting an inspiration breath pressure threshold for the pressure sensor based on the determined average breathing rate.
