Which item is NOT a standard intraoperative monitoring modality?

Explanation:
Intraoperative monitoring centers on real-time physiologic data you can respond to immediately. ECG provides continuous heart rhythm and rate, SpO2 shows how well the blood is being oxygenated, and end-tidal CO2 reflects ventilation and CO2 elimination during anesthesia. Serum bilirubin, by contrast, is a laboratory indicator of liver function or biliary issues that changes slowly and requires blood tests with lab processing—not rapid, actionable feedback during a procedure. Because bilirubin doesn’t provide the immediate, dynamic information needed to guide intraoperative decisions, it isn’t considered a standard intraoperative monitoring modality, whereas ECG, SpO2, and end-tidal CO2 are.
