OXYGEN CONCENTRATOR APPARATUS AND METHOD OF DELIVERING PULSES OF OXYGEN

摘要

An oxygen concentrator may rely on a pressure swing adsorption process to produce an oxygen enriched gas stream from canisters filled with granules capable of separation of oxygen from an air stream. The adsorption process uses a cyclical pressurization and venting of the canisters to generate an oxygen enriched gas stream. The oxygen concentrator system may deliver oxygen as one or more pulses of oxygen per breath.
