Abstract
An oxygen concentrator for supplying supplemental oxygen to a patient. The oxygen concentrator is adapted to supply supplemental oxygen directly to the patient and/or to a cylinder filler which is controlled to automatically fill a portable oxygen cylinder for use by an ambulatory patient. The cylinder filler is controlled to check the initial gas pressure in the cylinder prior to filling. If the initial cylinder pressure is below a preset minimum pressure, the cylinder filler will not fill the cylinder so that an empty cylinder which may be contaminated cannot be filled.
