1-183. (canceled)
A method of providing oxygen enriched gas to a user of an oxygen concentrator, the oxygen concentrator comprising:
- at least two canisters;
- gas separation adsorbent disposed in at least two canisters, wherein the gas separation adsorbent separates at least some nitrogen from air in the canister to produce oxygen enriched gas;
- and
- a compression system coupled to at least one canister;
- the method comprising:
- automatically assessing at least a portion of an inhalation profile of the user during use of the oxygen concentrator;
- providing oxygen enriched gas produced by the oxygen concentrator to the user, wherein the frequency and/or duration of the delivery of the oxygen enriched gas is at least partially based on the assessed inhalation profile;
- and
- adjusting the frequency and/or duration of the provided oxygen enriched gas based on one or more changes in the assessed inhalation profile.
185-221. (canceled)
A method of providing oxygen enriched gas to a user of an oxygen concentrator, the oxygen concentrator comprising:
- at least two canisters;
- gas separation adsorbent disposed in at least two canisters, wherein the gas separation adsorbent separates at least some nitrogen from air in the canister to produce oxygen enriched gas;
- and
- a compression system coupled to at least one canister;
- the method comprising:
- automatically detecting user inhalations during use of the oxygen concentrator;
- automatically assessing a current breathing rate of the user based on detected user inhalations;
- providing oxygen enriched gas produced by the oxygen concentrator to the user from the oxygen concentrator, wherein the frequency and/or duration of the provided oxygen enriched gas is at least partially based on the automatically assessed breathing rate;
- and
- adjusting the frequency and/or duration of the provided oxygen enriched gas based on changes in the automatically assessed current breathing rate.
239-256. (canceled)
A method of providing oxygen enriched gas to a user of an oxygen concentrator, the oxygen concentrator comprising:
- at least two canisters;
- gas separation adsorbent disposed in at least two canisters, wherein the gas separation adsorbent separates at least some nitrogen from air in the canister to produce oxygen enriched gas;
- and
- a compression system coupled to at least one canister;
- an outlet system coupled to one or more of the canisters, wherein the outlet system comprises one or more conduits for providing oxygen enriched gas to a user;
- the method comprising:
- automatically assessing an inhalation air flow rate of the user based on detected inhalations of the user;
- providing oxygen enriched gas produced by the oxygen concentrator to the user from the oxygen concentrator, wherein the frequency and/or duration of the provided oxygen enriched gas is at least partially based on the automatically assessed inhalation flow rate;
- and
- adjusting the frequency and/or duration of the provided oxygen enriched gas based on changes in the automatically assessed inhalation flow rate.
