An unresponsive patient is rescued from an enclosed space after an oxygen-depleting extinguisher release. What is the immediate management?

The main idea here is to rapidly restore oxygenation and ventilation after a hypoxic exposure in an enclosed space. An unresponsive patient who cannot protect their airway needs immediate assistance to breathe and to receive high concentrations of oxygen. Using a bag-valve mask lets you manually ventilate and deliver near-100% oxygen right away, giving you control of airway patency and ventilation while you assess the patient and continue care. Relying on a nonrebreather mask isn’t ideal in this situation because it depends on the patient’s own breathing to achieve oxygen delivery and doesn’t reliably support ventilation in an unresponsive or apneic patient. Intubation isn’t the first step either; it’s considered after you’ve established that ventilation with a bag-valve mask is insufficient or if a definitive airway is required for ongoing ventilation and protection of the airway. Providing no oxygen would leave the patient hypoxic, which is unsafe in this scenario.
