Item Summary for PURITAN BENNETT Nellcor companion 590 Oxygen Concentrator

Nellcor Puritan Bennett Oxygen Concentrator Companion 590:



Oxygen Concentrators take normal room air and, using a series of sieves, filters, and a compressor, remove 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.

Oxygen concentrators run on AC power and are normally used in clinical situations where the patient is bedridden or immobile at least part of the time, to conserve more portable oxygen tanks. They have a nine-volt battery which powers and alarm in case the AC plug is disconnected during operation, and have automatic low and high-pressure and overheating alarms and shut-offs. Also alarm if oxygen percentage drops below a certain level, usually at about 73%.
