After a gunshot wound, a patient is unresponsive with shallow respirations and an O2 saturation of 90%. What is the priority intervention?

The priority intervention in this scenario is assisting ventilation with a bag-mask device. Given that the patient is unresponsive and exhibiting shallow respirations, they are at significant risk for inadequate ventilation and severe hypoxia.

By using a bag-mask device, you can deliver effective positive pressure ventilation to ensure that the patient receives sufficient oxygen. This intervention directly addresses the immediate threat to the patient’s airway and breathing, which is critical in hypoxic situations following severe trauma such as a gunshot wound. Maintaining adequate ventilation is crucial because it directly impacts oxygenation and can prevent the rapid deterioration of the patient's condition.

While administering supplemental oxygen might seem important, it becomes less effective if the patient cannot adequately ventilate on their own. Providing IV fluids and performing a rapid trauma assessment, although relevant in trauma care, are secondary to re-establishing effective ventilation and ensuring the airway is protected. The highest priority must always be given to ensuring adequate oxygenation and ventilation, especially in a patient who is unresponsive.
