What percentage of nitrous oxide should be initiated at the beginning of sedation?

When initiating nitrous oxide sedation, starting at 10% is standard practice because it provides a safe and effective concentration for achieving the desired sedative effects while minimizing potential side effects. This percentage allows the patient to acclimate to the nitrous oxide without overwhelming them, allowing clinicians the opportunity to assess each patient's response before adjusting the dosage. Beginning at a lower concentration such as 10% also helps in ensuring that any potential anxiety or discomfort is managed effectively without risking over-sedation, which is important in dental and clinical settings.

This method of starting at modest levels is common in sedation protocols, allowing for a gradual increase in concentration based on patient tolerance and comfort, ensuring a safe and controlled experience during procedures.
