Who needs an oxygen concentrator?
Everyone has to breathe air to live a healthy life. So if someone has lung disease or other medical conditions that make it difficult to breathe from the air then oxygen therapy requires an oxygen concentrator.
How long can it supply oxygen?
The oxygen concentrator is different from canned oxygen and never runs out of oxygen because it filters out carbon dioxide, nitrogen and delivers only oxygenated pure air. It requires electricity to run.
Do I need a prescription?
Yes, a doctor's prescription is required to use the oxygen concentrator effectively. Otherwise it can be harmful without being beneficial. It can supply oxygen at different levels so the patient will get oxygen as per the doctor’s advice.
