What should be done if a patient shows signs of distress during nitrous oxide sedation?

When a patient exhibits signs of distress during nitrous oxide sedation, the appropriate action is to stop the nitrous oxide delivery and assess the situation. This approach prioritizes the patient's well-being and safety. By ceasing the delivery of nitrous oxide, the clinician can evaluate the patient's response, determine the cause of the distress, and take necessary steps to alleviate any discomfort or anxiety.

Continuing sedation or increasing the dosage could exacerbate the situation and potentially lead to more serious complications, such as increased respiratory depression or further anxiety. Engaging with the patient to assess their feelings is important; however, addressing the immediate physiological impact of nitrous oxide is crucial. Stopping the procedure momentarily allows for a clear assessment of the patient's condition and ensures that any necessary interventions can be implemented without further distress.
