Why is monitoring oxygen saturation critical in the PACU?

Monitoring oxygen saturation in the Post-Anesthesia Care Unit (PACU) is critical because it helps assess ventilation effectiveness. After undergoing anesthesia, patients are at risk for respiratory complications, including hypoventilation, which can lead to inadequate oxygenation. By continuously monitoring oxygen saturation levels, healthcare providers can quickly identify whether the patient is receiving adequate oxygenation.

A low oxygen saturation reading can indicate that the patient may not be ventilating effectively and may need interventions such as supplemental oxygen, repositioning, or more significant respiratory support. This monitoring is essential for ensuring that the patient maintains stable respiratory function as they recover from anesthesia, allowing for timely responses to any complications that may arise.

While assessing the need for discharge, pain levels, and medication administration are also important aspects of a PACU nurse's responsibilities, they are not directly related to the primary purpose of monitoring oxygen saturation, which is fundamentally linked to evaluating the patient's respiratory status.
