When blood glucose is critically low and the patient is unresponsive with compromised breathing, securing the airway and rapidly correcting the hypoglycemia are the top priorities. Placing an oropharyngeal airway helps keep the airway open when the patient is unresponsive and may have a partial airway obstruction from the tongue, allowing better ventilation without needing immediate intubation. At the same time, giving glucagon intramuscularly provides a fast, readily available means to raise blood glucose when IV access may be delayed or unavailable; the adult dose is 1 mg and it stimulates hepatic glucose release quickly.

Naloxone isn’t indicated here since there’s no signs pointing to opioid overdose, and simply giving high-flow oxygen or waiting for more vitals won’t address the life-threatening hypoglycemia. Re-attempting IV access and using a NRB mask come after airway management and glucose treatment, not before, given the immediate risk to airway and circulation.
