Abstract
A fractionator produces an oxygen enhanced gas for use in oxygen inhalation therapy. The fractionator includes an air source for supplying air, and a plurality of columns for containing an adsorbent material for adsorbing nitrogen gas. Each of the columns has first and second open ends. Air is directed from the air source to the column through the first open ends of the respective columns. A temperature sensor detects the temperature of the side wall of one of the columns. The fractionator changes the time for adsorption of nitrogen gas to the adsorbent material based on the detected temperature.
