What type of mask is used to deliver 100% oxygen to a patient?

• A. Nasal cannula
• B. Simple face mask
• C. Venturi mask
• D. Non-rebreather mask

Answer: (D)

The non-rebreather mask is specifically designed to deliver a high concentration of oxygen, often close to 100%, to a patient. This is achieved through a combination of a tight seal around the face, which minimizes room air intake, and a reservoir bag that allows the patient to inhale oxygen from the bag while preventing exhaled air from being drawn back into the reservoir. This mask typically has one-way valves that prevent the backflow of exhaled gases, ensuring that the patient receives the maximum amount of oxygen available. Such a mask is critical in situations where patients are experiencing severe respiratory distress or hypoxia, requiring immediate access to high-flow oxygen therapy.
