The air that we breathe is made up of:
- 21% oxygen
- 78% nitrogen
- 1% other gases
An oxygen concentrator works by drawing in the air. It separates the oxygen from the other gases using a filter system that allows only the oxygen to pass through. The patient breathes the oxygen as normal via their mask. Other people in the room will still be breathing normal amounts of oxygen.
The concentrator can be used with a long section of oxygen tubing to reach around the house.
The concentrator is about the size of a stand-alone gas heater and plugs into the mains electricity supply in the home, using 300 Watts (or below) per hour (about the same as four light bulbs). A back-up cylinder is sometimes provided to use in case of a power failure.
Portable oxygen concentrators
Portable concentrators continually provide oxygen, so the patient does not have to transport multiple tanks to avoid running out of oxygen. They run on a battery that needs to be recharged regularly.
Portable concentrators give the patient the ability to switch from AC electrical power at home, to DC power in the car, to battery power when walking, for maximum mobility.
They can be used on airplanes, but different airlines have different rules and the patient should check with the airline in advance of flying.
Oxygen concentrator with Self Filling system and portable cylinders
UltraFill® is an advanced home oxygen system that combines a stationary oxygen concentrator and a filling station. It comes with two long-lasting cylinders. The system is suitable for a wide range of needs experienced by many different types of oxygen patients, including those who are highly active or who require continuous and/or pulsed flow oxygen.
The concentrator unit takes oxygen from room air, filters it to the correct concentration and provides it to the filling station. Then the oxygen is compressed into a cylinder which can then be used for the patient’s mobility (ambulatory) requirements.
The oxygen concentrator can be used while filling the cylinder. This gives the patient a continuous oxygen supply both in the comfort of their own home and when out and about.
