Pulsed pressure swing adsorption system and method

An oxygen concentrator system comprising:

• a pressure swing adsorption (PSA) system including:
• a gas outlet configured to selectively flow oxygen enriched gas or pressurized air to a user of the oxygen concentrator;
• wherein the PSA system is configured to execute a PSA cycle to produce the oxygen enriched gas;
• a sensor in communication with the gas outlet and the PSA system;
• wherein the sensor is configured to sense a breathing cycle of the user;
• wherein the breathing cycle includes an inhalation phase and an exhalation phase;
• wherein:
• the inhalation phase includes a useful period and a dead space period;
• the dead space period occurs between the useful period and the exhalation phase;
• and
• wherein the PSA system is further configured to actuate a flow of the pressurized air via the gas outlet at the beginning of the dead space period of the inhalation phase.

An oxygen concentrator system comprising:

• a gas outlet configured to flow an oxygen enriched gas to a user of the oxygen concentrator;
• the oxygen concentrator system configured produce the oxygen enriched gas;
• a sensor in communication with the gas outlet and the oxygen concentrator system;
• wherein the sensor is configured to sense a breathing parameter of a breathing cycle of the user;
• wherein:
• the breathing cycle includes an inhalation phase and an exhalation phase;
• each respective breath is immediately preceded in the breathing cycle by a preceding breath and is immediately succeeded in the breathing cycle by a succeeding breath;
• the exhalation phase includes a non-useful period and a pre-inhalation period;
• the pre-inhalation period occurs between the non-useful period of the respective breath and the inhalation phase of the succeeding breath;
• wherein the oxygen concentrator system is further configured to:
• receive, from the sensor, a breathing input defined by the breathing parameter;
• and
• determine for each respective breath, using the breathing input, the beginning of the pre-inhalation period of the exhalation phase.
