Study notes
A very anxious patient needs a long procedure. Why might nitrous oxide be chosen over oral sedation? Nitrous oxide–oxygen sedation acts within minutes and wears off within minutes of stopping the gas, so recovery is fast and the level can be titrated moment to moment. Oral sedatives take longer to act, last hours, and cannot be quickly reversed — the patient needs an escort home. Teaching compares these profiles so students understand why titratability and rapid recovery matter in dental settings.
