When using nitrous oxide, what must be continuously monitored?

• A. The patient's heart rate
• B. The patient's oxygen saturation
• C. The patient's blood pressure
• D. The patient's respiratory rate

Answer: (B)

Continuous monitoring of the patient's oxygen saturation is crucial during the administration of nitrous oxide because it directly assesses the adequacy of the patient’s oxygen supply. Nitrous oxide can produce sedation and potentially depress the respiratory drive, which can lead to hypoxia if not closely monitored. Maintaining adequate oxygenation is vital to prevent complications such as respiratory depression or unconsciousness. Monitoring oxygen saturation allows for the immediate detection of any drops in oxygen levels, enabling swift intervention if necessary. This is especially important in dental settings where sedation is often used, as the patient may not fully communicate their experience during the procedure. While monitoring a patient's heart rate, blood pressure, and respiratory rate is also important for comprehensive patient care and safety, oxygen saturation specifically correlates with the immediate effects of nitrous oxide on the patient’s respiratory function and overall safety during sedation.
