The Nitronox® Field Unit provides convenient, safe and effective non-opioid pain relief. Nitronox offers on-the-spot inhalation analgesia to suffering patients at the scene of an injury and during transport. Advanced features protect your patients, including:


  • Preset 50/50 - N2O/O2 Mixture - neither the patient nor medical personnel are able to adjust the mixture - eliminating the risk of delivering a hypoxic mixture.
  • Oxygen-Driven Pressure Control - designed to immediately shut off N2O in the event of oxygen supply depletion.
  • Audible Alarm - for added safety a continuous alarm will sound should the device fall out of calibration or N2O depletion.
  • O2 Enrichment Feature - in case of shallow breathing (100 - 200 cc tidal volume) the Nitronox unit will automatically increase O2 concentration.
  • Patient Self-Administered - a patient hand held supply valve is activated only by an inspiratory effort.
  • 100% O2 Capability - in the event of N2O depletion, the unit provides 100% oxygen to the patient.
  • The Nitronox Field Unit conveniently connects to a small portable N2O cylinder and your existing O2 supply.
