In the past ten years, oxygen concentrators have grown in popularity and in the diversity of available models--but not in size. Miniaturization has been the major trend. Important factors in the choice and evaluation of oxygen concentrators are the size of the unit, concentrations and air flows delivered, reliability, and cost.
