Home oxygen concentrators were developed as a flexible and cost-effective way for those who have been prescribed the use of oxygen therapy by the physician to reclaim their independence both at home as well as on holidays.
Using the atmospheric oxygen in the room as a raw material, this device uses a molecular sieve to separate the oxygen from the nitrogen and concentrate it from the usual proportion of 18% up to a maximum of 96%, making it suitable for oxygen therapy.
The best oxygen concentrators feature an electronic user interface so you can adjust the levels of oxygen concentration and delivery settings. You then inhale the oxygen through the nasal cannula or special mask. You generally measure the oxygen concentrator output in LPM (liters per minute).
Your doctor will determine what level of oxygen you need, which may vary at rest, during sleep, and when you exercise.
