Air Liquide Healthcare's Nitrous Oxide Cylinder

Nitrous Oxide

For hospitals, dental and healthcare facilities

Air Liquide Healthcare is a leading supplier of medical nitrous oxide USP gas for dental, anaesthetic, and other applications.


Medical nitrous oxide is used in adults and children for:


  • General anaesthesia – usually as an adjuvant to other volatile or intravenous anaesthetics
  • Pain relief – employed with oxygen for analgesia in moderately painful procedures, such as dentistry, obstetrics, and fractures
  • Conscious sedation


Nitrous oxide is sometimes used as an adjuvant of balanced anesthesia for surgical interventions, enabling reduced doses of other drugs and facilitating their post-operatory elimination.
