Which monitoring modalities are standard in the intraoperative period for major surgery?

Explanation:
Intraoperative monitoring focuses on real-time assessment of oxygenation, ventilation, and circulation. Continuous ECG tracks heart rhythm and rate, so you can detect ischemia or arrhythmias as they arise. Pulse oximetry (SpO2) provides ongoing measurement of arterial oxygen saturation, enabling immediate detection of hypoxemia. End-tidal CO2 monitoring (capnography) gives quick feedback on ventilation and perfusion, helps confirm correct airway placement, and reveals issues like hypoventilation, obstruction, or changes in circulation. Serum bilirubin, however, reflects liver function over time and does not change acutely during surgery, so it isn’t a standard intraoperative monitor for guiding immediate management. In practice, others like arterial BP monitoring and urine output are also used, but theStandard intraoperative monitors among the options are ECG, SpO2, and end-tidal CO2.
