Used Puritan Bennett Home Concentrator Description
The Nellcor Puritan Bennett 590 Oxygen Concentrator takes normal room air and, using a series of sieves, filters, and a compressor, removes the Nitrogen from the air, thereby increasing the oxygen content of the resulting air to up to 96%. They are used by patients with chronic respiratory ailments. The resulting concentrated oxygen is then delivered via an output tube from the unit to either an oxygen mask, tracheotomy mask or connector, or to a nasal cannula. A flow adjustment knob on the front panel controls oxygen output in liters/minute and allows adjustment from 0.5 or 1.0 up to 5.0 liters/minute, depending on the particular model.
