Portable Oxygen Concentrator

 A Portable Oxygen Concentrator (POC) is a lightweight, battery-powered device that delivers oxygen via pulse dose technology, enabling active, mobile lifestyles for patients with chronic lung disease. By providing oxygen on-demand with each breath, it maximizes battery efficiency and portability, allowing users to travel, exercise, and socialize freely. It is a prescription-only device that requires careful titration to match a patient's needs during activity and is not a substitute for a stationary concentrator used at home and during sleep. Key considerations include FAA approval for air travel, battery life management, and understanding its specific use case as an ambulatory aid, not a primary oxygen source.
