Endotracheal intubation is most appropriate when there are two rescuers during a cardiac arrest. With two people, one can place and confirm the tube while the other maintains continuous, high-quality chest compressions, minimizing interruptions. A secured airway also provides reliable ventilation and better protection against aspiration during prolonged resuscitation. In other scenarios, such as an awake patient with airway obstruction, or when a nonrebreather is effectively meeting ventilation needs, or when rapid airway management with a supraglottic device is preferred due to speed or difficulty, intubation isn’t the best first choice.
