Nitrous Oxide 


Nitrous oxide is an anesthetic. Mixed with oxygen, it is also used as an antalgic (which attenuates the feeling of pain). It is used for the management of pain related to short but painful medical treatments (spinal taps, fractures, sutures, etc.), for anxiety management in patients who fear dental treatments and for the discomfort associated with childbearing. It is also an adjuvant of balanced anesthesia for surgical interventions, enabling reduced doses of other drugs and facilitating their post-operatory elimination.

Bulk Nitrous Oxide Systems

Nitrous Oxide systems typically have the reserve supply and the dual line controls located inside the facility. The control panel is set up to regulate the incoming pressure from the main and reserve supply sources and reduce it to the customer’s houseline requirement. This is typically between 45 and 55 psig for hospitals.
