What is a common sign of respiratory distress that PACU staff should monitor?

Low oxygen saturation levels are a critical indicator of respiratory distress that staff in the Post Anesthesia Care Unit (PACU) must be vigilant about monitoring. Adequate oxygenation is crucial for patient recovery, especially after anesthesia and surgery, as these procedures can affect the respiratory system. A drop in oxygen saturation can signify that a patient is not getting enough oxygen into their bloodstream, which could lead to complications such as hypoxemia or respiratory failure.

Unlike heightening alertness, which is generally a positive sign, low oxygen saturation reflects an immediate need for medical intervention. A decrease in blood pressure and increased appetite are not direct indicators of respiratory distress. Blood pressure fluctuations can have various causes and aren't solely related to respiratory function, while appetite is not relevant in the immediate recovery context. Monitoring oxygen levels, typically using pulse oximetry, is essential for ensuring that the patient maintains adequate respiratory function as they recover from anesthesia.
