Abstract
A portable oxygen concentrator designed for medical use where the usable life of the sieve beds, adsorbers, is monitored and communicated to the user or service provider through a user interface or a transmitted signal. The concentrator is designed so that the beds are easily replaced by the user or a field technician. Preferably PSA cycle operating parameters appropriate to the replaced beds can be easily reset if needed by the user or service provider.
