What is a key characteristic of a Venturi mask?

A Venturi mask is specifically designed to deliver a precise concentration of oxygen to patients, which makes it particularly useful in managing conditions like COPD (Chronic Obstructive Pulmonary Disease). The mask utilizes the Venturi principle, where a specific jet of oxygen is directed through a narrow nozzle, creating a negative pressure that draws in room air at a controlled ratio. This allows for accurate mixing of oxygen and ambient air, ensuring that the patient receives a consistent and specific concentration of oxygen.

This precision in oxygen delivery is critical in clinical settings, where maintaining target oxygen saturation levels is necessary for patient safety and effective treatment. The device is available with various interchangeable color-coded adapters, each designed to deliver a different set concentration of oxygen, which enhances its ability to provide consistent and measured dosage based on individual patient needs.
