What is the typical flow rate setting for nebulizers on the flowmeter as described in the material?

• A. 6-8 L/min.
• B. 2-4 L/min.
• C. 10-12 L/min.
• D. 12-16 L/min.

Answer: (A)

Nebulizers driven by an oxygen flowmeter work best with a moderate driving gas flow to generate a stable aerosol. The typical setting is 6–8 L/min. This range provides enough flow to produce a consistent fine mist and carry it to the patient without wasting oxygen. Using too little flow (2–4 L/min) often yields weak aerosol production and poor drug delivery, while higher flows (10–12 or 12–16 L/min) are generally used for other devices or high-flow therapy and aren’t typical for standard nebulization.
