Which device delivers a flow of 15 LPM?

• A. Nebulizer
• B. Nasal Cannula
• C. Non-Rebreather Mask
• D. Bag Valve Mask

Answer: (D)

Understanding how much oxygen a device can deliver helps you choose the right tool in resuscitation. A bag-valve mask with an oxygen reservoir is designed for active ventilation. When you squeeze the bag and it’s connected to an oxygen source, it pushes a high, controllable flow toward the patient—roughly 15 liters per minute—with each ventilation. That reliable, high-flow delivery is why it’s the device associated with a 15 LPM flow. In contrast, a nebulizer is used to deliver medicated aerosols and runs at lower, medication-specific flow rates (not the same high-volume oxygen delivery). A nasal cannula only provides a small, fixed range of flow (about 1–6 L/min). A non-rebreather mask can reach up to 15 L/min as its maximum oxygen flow, but that delivery is passive and depends on the patient’s breathing and seal; it does not guarantee the same active, full-volume ventilation that a bag-valve mask provides when you squeeze the bag. So, the bag-valve mask is the best answer for delivering a high, controllable flow around 15 LPM.
