What is the primary function of a Venturi mask?

The primary function of a Venturi mask is to deliver specific concentrations of oxygen by mixing it with air. This is achieved through the design of the mask, which uses the Venturi principle to allow precise control over the oxygen concentration delivered to a patient.

The mask has different color-coded adapters that correspond to specific flow rates and oxygen concentrations. By controlling the airflow through these adapters, healthcare providers can ensure that patients receive a consistent and accurate percentage of oxygen, which is especially important for those with conditions that require careful management of oxygen levels, such as COPD.

This precision makes the Venturi mask preferable in situations where it is critical to avoid both hypoxia and hyperoxia, ensuring that patients receive the most appropriate care based on their oxygenation needs.
