What type of oxygen delivery device is used to provide a high concentration of oxygen?

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

Answer: (D)

A non-rebreather mask is the device designed to deliver a high concentration of oxygen to patients. It consists of a mask that fits over the nose and mouth, equipped with a one-way valve that prevents exhaled air from entering the bag and allows for the inhalation of a high concentration of oxygen from the attached oxygen source. The reservoir bag must remain inflated during inhalation, which ensures that a high volume of oxygen can be delivered directly to the patient. In contrast, other devices, like a nasal cannula, provide a lower concentration of oxygen, typically ranging from 24% to 40%. A simple face mask generally provides a concentration of about 40% to 60% oxygen but doesn’t offer the same level of oxygen saturation as a non-rebreather mask. The Venturi mask is designed to deliver precise concentrations of oxygen using different color-coded adapters, but it does not provide the high concentrations that a non-rebreather mask does. Therefore, for delivering a high concentration of oxygen, the non-rebreather mask is the most effective choice.
