What are the indications for using supplemental oxygen in the PACU?

In the Post-Anesthesia Care Unit (PACU), the primary indication for using supplemental oxygen is hypoxemia or low oxygen saturation levels. After anesthesia, patients may experience respiratory depression or compromised lung function, leading to inadequate oxygenation. Supplemental oxygen is administered to ensure that the patient receives sufficient oxygen to maintain adequate tissue perfusion and prevent complications associated with hypoxia, such as cardiac arrhythmias or organ dysfunction.

Monitoring oxygen saturation levels is vital in the PACU, as it helps clinicians determine whether a patient requires supplemental oxygen. When saturation levels drop below a certain threshold, typically around 92% depending on institutional protocols and patient conditions, supplemental oxygen is indicated to improve respiratory status. This intervention is crucial for promoting recovery and ensuring patient safety during the post-anesthesia period.

Other conditions listed, such as excessive bleeding, dehydration, or elevated blood pressure, may require different interventions but do not directly indicate the need for supplemental oxygen in the same way that hypoxemia does.
