Abstract A gas fractionalization apparatus and methods for providing oxygen rich air to patients are disclosed. The apparatus comprises a variable output compressor, a PSA unit, a control system, and one or more pressure sensing devices. Pressure of the oxygen rich gas is maintained within a selected window by adjusting the output of the compressor in response to changes in the pressure of the oxygen rich gas. Methods of feedback control are further provided for calibration of the compressor under factory and in-service conditions, as well as under high-altitude conditions. Methods for providing diagnostic estimates and alarms of time to service are further provided. L'invention concerne un dispositif de fractionnement de gaz et des procédés pour fournir un air riche en oxygène à des patients. Ledit dispositif comprend un compresseur à puissance variable, une unité d'absorption modulée en pression (PSA), un système de commande et un ou plusieurs dispositifs de commande. La pression du gaz riche en oxygène est maintenue dans une fenêtre sélectionnée, par ajustement de la puissance du compresseur en réponse aux changements intervenant au niveau de la pression du gaz riche en oxygène. L'invention concerne également des procédés d'asservissement pour échantillonner le compresseur dans des conditions d'usine et d'exploitation, ainsi que dans des conditions de haute altitude. L'invention concerne par ailleurs des procédés permettant de fournir des estimations diagnostiques et des alarmes de temps de service.
