AirJector•Vet is the world's only portable device for the transdermal treatment of medical conditions in animals.

• Noninvasive
• Painless
• Easy to use
• Portable
• Low Cost


Medical therapy through the skin is a well-described practice. Transdermal applications of patches containing medicine for treating pain, nausea, heart failure, and dementia are commonplace. All these regimens permit the prolonged transfer of drugs into the body, so there is a continuous amount of the drug in the bloodstream. An alternative option for transdermal therapy is to use a gas, instead of a patch. The use of gas has been less common due to the difficulty in transporting the gas and administering it in a controlled fashion. AirJector•Vet solves those issues and allows veterinarians to offer this therapeutic option in an easy to use, portable and low cost format.

The AirJector•Vet uses pharmacopeia grade medical gases to vaporize warm water into a therapeutic mist that is enclosed around the therapy site in a sealed environment of pure gas. This sealed atmosphere maximizes continuous transfer of gas into the tissue for the full twenty to thirty minute therapy cycle.

Airjector•Vet & The Power of CO2

Laboratory studies in cells, animals and humans clearly demonstrate that carbon dioxide has many potential mechanisms for treating a variety of diseases.

Transdermal carbon dioxide dramatically increases tissue blood flow and oxygenation. It also decreases concentration of HIF1 alpha and it directly decreases the main biological compound that regulates inflammation (NFkB). And, transdermal carbon dioxide has a powerful role in reducing the reactive oxygen species (ROS) thus ameliorating the ROS activity.

Additional biological benefits of CO2 include:

  • Increased nitric oxide thus enhancing flow dependent dilation

  • Increased mitochondrial biogenesis

  • Promotion of VEGF upregulation

  • Neovascularization and capillary growth

  • Activation of myogenesis thus accelerating muscle injury repair over fibrosis

  • Suppression of the growth of metastic squamous cells and osteosarcoma

Clinical research has shown positive effects of transcutaneous carbon dioxide in treating peripheral vascular disease, exercise endurance, skin grafts, wound healing, muscle disuse, tumorigenesis, and bone fractures. In addition, there is every reason to predict positive effects for laminitis; although, it has not yet been tested.

The CO2 treatments had a direct and positive effect on improving degree of lameness and a likely positive effect by accelerating lesion healing and reducing inflammation. Transdermal CO2 treatments are likely to be an appropriate adjunctive therapy for treating soft tissue inflammation and distal suspensory ligament injuries to accelerate healing, reduce inflammation, with a result of improved overall lameness scores

Airjector•Vet in Practice

The benefits of CO2 therapy, when coupled with the ease of use and affordability of treatments, make equine and canine athletes ideal candidates for transdermal carbon dioxide therapy.

Treatments can be delivered in the hospital, the barn, the paddock or the pasture. No excessive training is necessary. While CO2 must be administered under the supervision of a veterinarian, any member or the staff or even the animal's owner or trainer can deliver the treatments.

Our recommended standard protocol is to treat the condition for twenty minutes every day for five days and then every other day for seven additional treatments. In some cases, such as fractures, soft tissue injuries, slow healing wounds  and lesions deep within the limb, additional treatments may be necessary. 

The CO2 treatments used on a laceration involving the entire surface of the carpus allowed for a dramatically shortened healing time but also avoided the cost of hospitalization for a skin graft.
