A method of determining the purity of oxygen present in an oxygen-enriched gas produced from an oxygen delivery system is disclosed. The oxygen delivery system includes at least one sieve bed having a nitrogen-adsorbing material disposed therein and configured to adsorb nitrogen from a feed gas introduced into the at least two sieve beds via a pressure-swing adsorption cycle. The method includes determining a quantity of nitrogen adsorbed by the nitrogen-adsorbing material by inferring an effective volume of the at least one sieve bed based on a pressure change of the at least one sieve bed.
