What is the most appropriate action for a patient in Phase 1 PACU who is unresponsive and has a respiratory rate of 12?

In the situation described, where a patient in Phase 1 PACU is unresponsive and has a respiratory rate of 12, inserting an oral airway is the most appropriate action. The patient's unresponsiveness indicates a potential compromise in their airway patency. An oral airway can help maintain an open airway, facilitating effective ventilation by preventing the tongue from obstructing the airway. This intervention is critical in a post-anesthesia setting where airway stability is paramount.

Depending on the level of sedation and the patient’s responses, the respiratory rate of 12 breaths per minute, while on the lower edge of normal, could suggest hypoventilation. Inserting the oral airway can assist in improving ventilation and oxygenation while further assessments and interventions are initiated.

While administering oxygen and positioning the patient may also be relevant, the immediate prioritization must be maintaining an open airway to ensure adequate ventilation. Contacting the surgeon is important for serious concerns, but airway management takes precedence in this scenario.
