Venturi Mask is a precision oxygen delivery interface that uses color-coded diluter valves to deliver a fixed, known FiO2 regardless of the patient's respiratory pattern. It is the preferred interface when accurate FiO2 delivery is clinically critical — particularly for patients with COPD where precise oxygen concentration is important to avoid suppression of the hypoxic drive.

OxyCare supplies Venturi masks with the appropriate diluter valves for the prescribed FiO2, and can advise on the correct valve selection for each patient's oxygen prescription.
