Which description matches a Face Mask (FM) for oxygen delivery?

• A. A plastic mask fit over the nose and mouth.
• B. A nasal cannula in the nostrils
• C. An ETT through the mouth
• D. A mask with reservoir bag

Answer: (A)

A face mask for oxygen delivery is a plastic device that fits over the nose and mouth to deliver oxygen into the airways. This is different from a nasal cannula, which sits in the nostrils, and from an endotracheal tube, which is placed into the trachea through the mouth. A mask with a reservoir bag describes a specific type of mask that includes a bag to hold extra oxygen for higher concentrations, but the basic description of a face mask is simply a plastic mask that covers the nose and mouth.
