The air we normally breathe is a mixture of oxygen, nitrogen and trace gases. An oxygen concentrator is a device used to separate oxygen from room air allowing the oxygen to pass through a nasal cannula, mask or other delivery device for the benefit of the patient.
Your physician has determined, as a result of your current condition that supplemental oxygen will be of benefit to you and has prescribed the use of an oxygen concentrator to provide this supplemental oxygen. A prescribed setting, of the oxygen concentrator, has been established to meet your related needs. Changes to these prescribed settings should only be made under the advice of your physician.
