An oxygen concentrator is a medical device designed to increase the delivery of oxygen to the lungs by filtering the air in the atmosphere to produce a concentrated oxygen supply. This device is equipped with a series of filters and sieves that remove nitrogen and other gases from the air, resulting in an oxygen-rich gas that is delivered to the patient through a mask or nasal tube. Oxygen concentrators can be used in various settings, including hospitals, clinics, and homes, to provide oxygen therapy to patients suffering from breathing difficulties. They are particularly useful for patients with chronic respiratory diseases, such as chronic obstructive pulmonary disease (COPD), pneumonia, and cystic fibrosis. The benefits of oxygen concentrators include improved oxygen levels in the blood, reduced shortness of breath and fatigue, increased mobility and
