Oxygen concentrator machines are essential medical devices that provide pure and additional oxygen to people with breathing problems, such as chronic obstructive pulmonary disease (COPD), severe sleep apnea, severe chronic hypoxemia, and pulmonary edema. These machines work by drawing in air and filtering out bacteria, dust, and other microscopic particles. The purified oxygen is then delivered to the patient, while nitrogen is released back into the air.

The concentrator unit consists of a compressor, sieve bed filter, tubing, and accessories such as nasal cannula and face mask. The sieve bed is typically made of a special Zeolite material that is used to separate nitrogen from oxygen. Some portable oxygen concentrators also come with an AC and DC charger, as well as a battery.

Oxygen Concentrators are medical devices that provide additional and pure oxygen to people with breathing problems, for example, chronic obstructive pulmonary disease (COPD), severe sleep apnea, severe chronic hypoxemia and pulmonary edema. It is easy to use, portable and cost-effective device extensively used in hospitals.
