Patients with chronic lung diseases sometimes use powered oxygenating machines, which enrich room air and deliver the result to the patient through (usually) nasal cannulae.

How do these oxygenating devices work?

The devices are called "Oxygen Concentrators". 

Apparently they would be better termed as a Nitrogen scrubber. 
Ambient air is brought into the system and compressed into a zeolite chamber. 
The zeolite absorbs the nitrogen out of the air, leaving the oxygen and other minor constituents (CO2, Argon, etc).
The concentrated Oxygen, is then transferred into another chamber for pressure equalization and delivery to the patient.
The pressure is reduced in the zeolite chamber releasing the nitrogen which is expelled from the system and the cycle is repeated.

==============

I had a neighbor who had bad emphysema and was dependent on oxygen bottles for doing just about anything outside, and I think he also had an oxygen concentrator for use in the house. 
Anyway, they decided to try him on positive airway pressure (PAP, or CPAP) at night.  The device works on by increasing pressure in the airways, and requires a full mask rather than a nasal cannula.  In my neighbor's case, however, he was able to almost completely wean off from requiring supplemental oxygen during the days.  It was a significant benefit for him.

Thanks Clifford. I'll squirrel that knowledge away for the future!
