A device used for home oxygen therapy that removes most of the nitrogen from room air and delivers the oxygen at a low flow rate.
A device utilized in oxygen therapy that segregates oxygen from the surrounding air and subsequently blends it to achieve a higher concentration. This enriched oxygen-air mixture is conveyed through a tube for extended inhalation. Individuals suffering from persistent hypoxia (insufficient oxygen in bodily tissues) due to severe chronic obstructive pulmonary disease utilize this device.
