How It Works
The diffuser streams high-pressure, carbon dioxide (CO2) gas at 70 bars pressure and -110°F to the affected site on the horse’s body. This creates a thermal shock that immediately activates the sensory neuroreceptors under the skin.
The horse’s central nervous system responds with a corrective reflex, which brings a reduction in inflammation, swelling and pain, with further muscular relaxation, within just 60 seconds.
4 Principle Effects
Analgesia
Treatment brings an immediate reduction in pain caused by joint, ligament and tendon issues, allowing horses to recover from acute and chronic lameness faster.
Anti-Inflammatory
Swelling decreases rapidly, while associated increases in blood flow enables faster healing of damaged soft tissue, especially with laminitic horses.
Muscular
Rapid resolution of post-exercise tension and pain from microtears reduces the risk of further tissue damage.
Cardiovascular
Blood vessels dilate leading to improve circulation, minimizing the possibility of further damage caused by poor blood flow to injury sites.
