    Study Notes

    Nitrous Oxide/Oxygen Sedation in Dentistry

    • Pre-procedural patient evaluation recommends not fasting but avoiding fatty foods before the procedure
    • Informed consent is mandatory and includes understanding the purpose, benefits, risks, and alternative options of nitrous oxide/oxygen sedation
    • Patient monitoring during sedation includes evaluating consciousness, pulmonary ventilation, and oxygenation
    • Personnel preparedness for emergencies includes current knowledge, training, emergency kit, AED, medications, and access to emergency services
    • Two main types of supply systems for nitrous oxide/oxygen sedation are central storage and portable gas delivery
    • Portable gas delivery system includes yoke stand, color-coded hoses, regulator, flowmeter, and reservoir bag
    • Safety features of nitrous oxide/oxygen sedation include oxygen fail-safe system, pin and diameter index, minimum oxygen liter flow, and O2 flush button
    • Tidal volume and minute volume are key factors in monitoring nitrous oxide/oxygen sedation
    • Titration of gases allows incremental administration of nitrous oxide to reach a desired level of sedation
    • Signs and symptoms of appropriate nitrous oxide/oxygen sedation include comfort, relaxation, reduced fear and anxiety, and tingling or warmth in extremities
    • Ideal sedation includes ability to respond to commands, slower eye movement, lightheadedness, and tingling/numbness
    • Signs and symptoms of nitrous oxide/oxygen oversedation include detachment from the environment, inability to move or communicate, drowsiness, dizziness, and potential unconsciousness
