The continuous monitoring after sedation includes which of these?

• A. SpO2 and Temperature
• B. Sugar monitoring only
• C. SpO2, Nasal EtCO2, ECG, and blood pressure
• D. ECG and Respiratory rate

Answer: (C)

After sedation, the patient’s safety relies on watching breathing and circulation constantly. SpO2 shows how well blood is carrying oxygen, while nasal EtCO2 (capnography) provides real-time insight into ventilation and airway status, often catching hypoventilation or obstruction before oxygen levels drop. ECG monitors heart rhythm and detects potential arrhythmias or ischemic changes, and continuous blood pressure checks reveal how well perfusion is being maintained. Taken together, these four measurements cover the critical systems affected by sedation, offering early warnings and enabling timely intervention. Temperature or glucose monitoring alone don’t address these acute respiratory and cardiovascular risks, and relying on only one or two modalities could miss developing problems.
