Dual flow oxygen concentrator is a medical device that delivers oxygen to two patients at the same time from a single machine, using two separate flow meters to adjust each user's oxygen supply. These concentrators are common in high-capacity settings like hospitals and clinics and are designed for patients with conditions like COPD, asthma, or pneumonia. Features often include a high flow rate capacity (typically up to 10 liters per minute), high oxygen purity (\(93\%\) or higher), and safety alarms for issues like pressure, temperature, or power failure.
