A patient is breathing shallowly at eight breaths per minute. What is the most appropriate intervention?

When ventilation is inadequate, the priority is to provide assisted ventilation. Breathing at eight breaths per minute with shallow breaths means the patient isn’t moving enough air to ventilate properly, so carbon dioxide can build up and oxygen delivery can fall. Simply giving oxygen isn’t enough because air isn’t being moved into the lungs reliably. Delivering positive-pressure ventilation with a bag-valve mask (ideally with high-flow oxygen) actively inflates the lungs and raises the rate and depth of breaths. This helps restore sufficient minute ventilation and improves both oxygenation and carbon dioxide removal. Sitting them up and encouraging breathing might help a little, but it won’t reliably correct the hypoventilation. Providing only a nasal cannula or a nonrebreather mask increases oxygen but doesn’t address the need for assisted breaths. So the best action is to initiate assisted ventilation with a bag-valve mask to support and normalize ventilation.
