A Venturi mask can deliver oxygen concentrations from 24% to 60% with flow rates from 4 to 12 L/min. Because this device delivers a precise oxygen concentration and carbon dioxide buildup is minimal, it is commonly used for patients who have COPD. Humidification is usually unnecessary with this device.
