Which statement is true concerning the use of a Venturi mask?

The statement regarding Venturi masks that focuses on the color-coded attachments regulating oxygen percentage is accurate because the Venturi mask is specifically designed to deliver a precise and stable concentration of oxygen to patients. Each color-coded attachment corresponds to a specific flow rate and the resulting oxygen concentration delivered, allowing healthcare providers to easily select the appropriate option for the patient's needs.

This mechanism is crucial for maintaining consistent oxygen levels for individuals who may have conditions requiring specific oxygen concentrations, such as chronic obstructive pulmonary disease (COPD). The ability to visually distinguish the attachments based on color simplifies the administration process and enhances patient safety by minimizing the risk of delivering incorrect oxygen concentrations.

In contrast, other statements about Venturi masks do not accurately characterize their function. For instance, the idea that the oxygen concentration is fixed and cannot be adjusted is incorrect, as the use of different color-coded attachments allows for varying oxygen concentrations. Moreover, claiming that it requires a complicated setup is misleading since the mask is relatively straightforward to use with a few attachments. Lastly, suggesting that it only delivers low concentrations of oxygen ignores the versatility of the mask, as it can provide a range of oxygen concentrations from low to moderate, allowing for more flexibility in treatment options.
