If a patient shows signs of confusion in the PACU, what should be your immediate concern?

When a patient displays signs of confusion in the PACU, assessing for hypoxia is crucial as it can often be a primary cause of altered mental status in the postoperative period. Hypoxia, or a deficiency in the amount of oxygen reaching the tissues, may lead to cognitive impairment, confusion, and other neurological deficits. In the context of the PACU, where patients are recovering from anesthesia, maintaining adequate oxygenation is of utmost importance, as anesthesia can affect respiratory function and oxygen levels.

Identifying hypoxia early allows for prompt intervention, such as administering supplemental oxygen or adjusting ventilation support, which can significantly improve the patient's condition and help prevent further complications. Thus, ensuring that the patient is adequately oxygenated is a top priority when they exhibit confusion.
