When a patient shows signs of hypoxia, what is the best immediate airway management option?

• A. Nasal cannula
• B. Bag-valve-mask
• C. Non-rebreather mask
• D. Oropharyngeal airway

Answer: (B)

The key idea is that hypoxia requires both opening the airway and providing ventilation with high-concentration oxygen as quickly as possible. A bag-valve-mask is the best immediate option because it allows you to actively give breaths and, when connected to an oxygen source, deliver high FiO2 to the patient. This twice-addresses the problem: it supports ventilation if the patient isn’t breathing adequately and also maximizes oxygen delivery.

Other devices can supply oxygen but don’t provide ventilation. A nasal cannula can deliver only modest oxygen and relies on the patient’s own breathing. A non-rebreather mask can deliver high oxygen levels, but it still depends on the patient’s own breaths and doesn’t ventilate if ventilation is insufficient. An oropharyngeal airway helps keep the airway open but does not oxygenate or ventilate on its own; it’s an adjunct used to facilitate other airway management, not a standalone solution for hypoxia.

So, using a bag-valve-mask immediately addresses both needs—ventilating and oxygenating the patient—making it the best immediate choice in a hypoxic scenario.
