Oxygen Concentrator

An oxygen concentrator is a medical device that delivers a continuous supply of concentrated oxygen to patients who have low oxygen levels in their blood. It works by taking in ambient air, filtering out nitrogen, and providing oxygen-rich air (usually around 90–95% purity) through a nasal cannula or mask. Unlike oxygen cylinders, concentrators do not require refilling — they continuously produce oxygen as long as they are connected to a power source.
