oxygen to individuals with breathing-related disorders. Individuals
whose oxygen concentration in their blood is lower than normal often
require an oxygen concentrator to replace that oxygen.
It`s
also equipped with special filters and sieve beds which help remove
Nitrogen from the air to ensure delivery of completely purified oxygen
to the patient. These devices also come with 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
