Pro-Nox™ provides immediate relief from pain and anxiety
Pro-Nox™ Nitrous Oxide Delivery System is a tool for managing pain and anxiety during various medical and aesthetic procedures. Pro-Nox is a patient-controlled inhaled analgesia system that delivers a fixed mixture of 50% Nitrous Oxide (N2O) and 50% Oxygen (O2). It’s designed to provide safe and comfortable relief from worry and discomfort during in-office procedures.
How Does Pro-Nox Work?
The system uses a specially designed on-demand valve that delivers the medical gases only when you inhale. You hold the mouthpiece or mask and breathe in and out as needed for relief. This allows you to control when and for how long you use the system, while remaining conscious and able to respond. The effect is a diminished sensation to pain without loss of consciousness.

Quick Effect and Recovery
The effects of Pro-Nox are typically felt within just a few breaths, offering immediate relief of pain and anxiety. There are no needles or pills involved. When you stop using the mouthpiece or mask and take normal breaths, the N2O is quickly expelled from your body, and the effects wear off rapidly.
Is Nitrous Oxide Safe?
A 50/50 mix of Nitrous Oxide and Oxygen has been used safely for decades in various medical settings, including aesthetics, labor and delivery, orthopedics, plastic surgery, urology, dermatology, hospitals, and surgery centers. Studies have shown that it is non-addictive and can even decrease the need for other pain medications.
