Study Notes

Nitrous Oxide (N2O) and Oxygen (O2) Use in Dentistry: Key Considerations

  • Nitrous oxide (N2O) is a sweet-smelling, colorless gas that readily crosses the blood-brain barrier and is eliminated through the lungs without biotransformation.
  • Oxygen (O2) is odorless, colorless, and tasteless in its gaseous state and can cause nausea as a common side effect, particularly with prolonged administration or rapid induction.
  • Complications of N2O use include hypoxia, psychologic reactions, and fire hazards due to its combustible nature.
  • The respiratory system includes the nose, pharynx, larynx, trachea, bronchi, bronchioles, alveolar ducts, alveolar sacs, and alveoli, with its primary function being gas exchange.
  • The nose warms incoming air, humidifies air, and filters macro and microparticles, and is the entry point for N2O and O2 into the respiratory system.
  • The patient assessment for N2O/O2 use involves absolute contraindications such as pneumothorax, cystic fibrosis, COPD, and special considerations including cardiovascular and hepatic diseases.
  • Pre-procedural patient evaluation includes obtaining vital signs, delivering verbal and written instructions, and ensuring the patient understands the procedure, potential symptoms, and the use of 100% oxygen post-procedure.
