What is the primary function of a Venturi Face Mask?

The primary function of a Venturi Face Mask is to deliver oxygen through a jet mixing device. This mask operates on the principle of Bernoulli's principle, which allows it to mix ambient air with a fixed flow of oxygen, thus delivering a precise oxygen concentration. The design of the mask includes various colored adapters or jets that correspond to different oxygen flow rates, enabling the healthcare provider to select the desired concentration of oxygen for the patient.

This capability is particularly beneficial in managing patients with chronic obstructive pulmonary disease (COPD) or other respiratory conditions where it is crucial to maintain adequate oxygen levels without causing respiratory drive suppression. The Venturi system ensures a consistent delivery of oxygen, regardless of changes in the patient's breathing pattern, thus safeguarding adequate oxygenation.

The other options do not accurately reflect the specific design and function of the Venturi Face Mask. For example, low-flow oxygen delivery and variable flow rates are characteristics of other types of oxygen delivery devices, while aerosolized medication administration is typically associated with nebulizers or metered-dose inhalers, not with a Venturi mask.
