For a semiconscious patient with cyanide exposure and inadequate breathing, the most appropriate method of providing assisted ventilations is to:

• A. Use a Bag-Valve Mask (BVM)
• B. Perform mouth-to-mouth ventilation
• C. Use a pocket mask without a device
• D. Deliver oxygen via nasal cannula only

Answer: (A)

When a semiconscious patient isn’t breathing adequately, you need a device that both protects the airway and delivers effective ventilation with a high concentration of oxygen. A bag-valve-mask with an oxygen reservoir does exactly that: it provides controlled, adequate tidal volumes and, with oxygen connected, delivers near-ambient to high FiO2 levels. This is crucial in cyanide exposure, where increasing oxygen delivery helps despite impaired cellular utilization, while you arrange rapid transport and any antidote therapy. Mouth-to-mouth ventilation is less reliable and increases exposure risk to the rescuer; a pocket mask without a reservoir limits both the quality of ventilation and the oxygen delivered; and a nasal cannula only provides oxygenation without ventilating the patient. Thus, the bag-valve-mask with reservoir is the best option for assisted ventilations in this scenario.
