Beschreibung
Zusammenfassung:	Apparatus, such as a portable oxygen concentrator (100) or other device communicating therewith, may be configured, such as with a processor(s), to estimate a remaining capacity of a sieve bed of the concentrator. Such apparatus may be configured to access a parameter of a measured pressure-time characteristic of the sieve bed for a phase of a pressure swing adsorption cycle of the oxygen concentrator. The apparatus may be configured to access function(s) of the parameter of the pressure-time characteristic and operational characteristic(s) of the sieve bed. The apparatus may be configured to estimate the remaining capacity by applying the function(s) to the parameter of the measured pressure-time characteristic. Such an estimate may then serve as a basis for providing notification, such as on a display or by electronic messaging, to inform of remaining life of the sieve bed, or otherwise promote timely replacement of a depleting component.
