투여 경로

금기

• Patients with air-filled spaces within the body (e.g., pneumothorax, gastric dilatation/GDV, intestinal obstruction)
• Marked respiratory compromise (due to hypoxia risks)
• Raised intracranial pressure (due to associated increases in cerebral blood flow)

이상반응

• Diffusion hypoxia (if oxygen is not supplemented upon discontinuation)
• Megaloblastic changes in bone marrow (with exposure lasting a few hours)
• Agranulocytosis (with prolonged exposure of a few days)

모니터링

• Inspired oxygen concentration (FiO2) - especially in rebreathing circuits
• Pulse oximetry (SpO2)
• Capnography (ETCO2)
• Respiratory rate and effort
• Cardiovascular parameters (HR, BP)

과용량

Overdosage primarily presents as **hypoxia** if the inspired oxygen concentration falls below 30%. Treatment consists of immediately discontinuing nitrous oxide and providing 100% oxygen via positive pressure ventilation if necessary.
