Selecting the correct oxygen concentrator is a difficult task considering the availability of various oxygen concentrators in the market. Although a physician will determine the amount of oxygen a patient needs, the exact device is not recommended. Therefore, the user could select an oxygen concentrator that is compatible to suit the lifestyle and usage.
