Abstract
This disclosure relates to a control system for a portable oxygen concentrator (POC). Specifically, this disclosure relates to a method and a system configured for use with an oxygen delivery system that includes nasal fitting which does not include nostril prongs. Because the nasal fitting does not include nostril prongs, user comfort is dramatically increased relative to prior designs. That said, because the fitting is free of nostril prongs, changes in pressure associated with the user's breathing register less than in oxygen delivery systems with traditional fittings (i.e., those that include nostril prongs). As such, the method and system of this disclosure is configured to associate relatively small changes in pressure with a breathing cycle of a user, thereby permitting effective and efficient POC operation.
