The document discusses standards for physiological monitoring during anesthesia. It states that monitoring must begin before induction and continue until recovery is complete. Essential monitoring includes pulse oximetry, non-invasive blood pressure, ECG, and assessment of respiratory gases and airway pressures. Additional monitoring of temperature and muscle relaxation is required if those interventions are used. Standards call for qualified staff to continuously evaluate oxygenation, ventilation, circulation and temperature throughout all anesthetics.
