Venturi mask with dilutors should be used when possible as they yield a precise fraction of inspired oxygen (FiO2) and provide a flow that exceeds the full ventilatory requirements. Available Venturi masks deliver an FiO2 of 24, 28, 31, 35, 40, or 60%. The design of the valve ensures that a specific proportion of oxygen and air are mixed and delivered to the patient.
With the Venturi mask system, oxygen inflow is connected to a specific color-coded entrainment device at the base of the mask that provides a set FIo2 at a set oxygen inflow rate. Various entrainment devices can provide an FIo2 of 0.24 to 0.5, with an oxygen inflow of 4 to 15 l/min and a total flow delivered to the patient (including entrained air) of 35 to 45 l/min. If the patient's peak inspiratory flow exceeds this total flow, a lower FIo2 is inspired. The Venturi mask is ideal for a patient with COPD who has a low to moderate oxygen requirement but is at risk for hypercarbia with uncontrolled oxygen therapy.
