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.

12. An oxygen concentrator apparatus, comprising:
-
a pressure sensor, the pressure sensor configured to detect a breath pressure of a user; and a processor operable coupled to the pressure sensor, the processor to execute non-transitory program instructions, and wherein the program instructions are operable to; automatically measure the time between a plurality of successive breaths, wherein a breath is determined to begin when a drop in pressure is measured using the pressure sensor; determine 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 set an inspiration breath pressure threshold for the pressure sensor based on the determined average breathing rate. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)

62. 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; creating groupings of breaths, wherein each grouping comprises at least three successive breaths; determining an average breathing rate for each grouping based on the time between each of the successive breaths within the grouping; and setting an inspiration breath pressure threshold for the pressure sensor based on the determined average breathing rate of two or more of the groupings.
