An **Oxygen Concentrator** is an advanced medical device that plays a crucial role in providing supplemental oxygen therapy to individuals suffering from various respiratory conditions, such as COPD, asthma, and emphysema. Unlike oxygen cylinders that store compressed gas, a concentrator **draws in ambient air and filters out nitrogen**, delivering a continuous stream of highly concentrated oxygen to the user. This innovative technology eliminates the need for frequent cylinder refills and the associated logistical challenges, making it a more convenient and cost-effective long-term solution. Oxygen concentrators come in stationary models for home use and smaller, portable versions for greater mobility. They are designed for continuous operation, providing a reliable and consistent oxygen supply, which is vital for improving blood oxygen levels, reducing breathlessness, and enhancing the overall quality of life for patients requiring oxygen therapy.
