Which statement is NOT an advantage of using a pocket mask?

• A. Has a one-way valve
• B. Allows the use of supplemental oxygen
• C. Can provide up to 80% oxygen at 6 L/min
• D. Provides a barrier between the patient and the paramedic

Answer: (C)

The main idea here is understanding what a pocket mask can reliably deliver while still protecting the rescuer. A pocket mask provides a barrier between you and the patient and includes a one-way valve to reduce exposure to bodily fluids. It also allows you to connect supplemental oxygen to help improve the patient’s oxygen intake. These are genuine advantages because they enhance safety and oxygenation during ventilation. However, the statement about delivering up to 80% oxygen at 6 L/min isn’t accurate for a pocket mask. Even when connected to oxygen, the oxygen concentration you can deliver with a pocket mask is limited by the mask design and the absence of a reservoir. Typically, FiO2 with a pocket mask and oxygen is in the roughly 40–60% range, not 80%, and you generally need a device with a reservoir—such as a bag-valve mask or a nonrebreather mask—to reach higher concentrations. So the claim about 80% at that flow rate is not an advantage of using a pocket mask.
