Overview
Veterinary hyperbaric chambers are hard-shell units sized for horses, dogs, cats, and exotic animals. Equine HBOT is a growing field in racing and performance recovery; small-animal HBOT is used for wound healing, post-surgical recovery, and specific neurological conditions.
Veterinary HBOT emerged in the 1990s and has grown substantially in equine performance medicine over the past decade. Thoroughbred and standardbred racing programmes use HBOT for soft-tissue injury recovery, tendon healing, and post-surgical convalescence. Equine chambers are large walk-in units at 2.0–3.0 ATA capable of accommodating a 1,200+ pound horse.
Small-animal veterinary HBOT uses smaller monoplace-style chambers for dogs, cats, and exotic patients. Indications include wound healing, post-surgical recovery, snake bite envenomation, acute spinal cord injury, and various inflammatory and ischaemic conditions. Veterinary HBOT is less regulated than human medical HBOT but increasingly practised at specialty veterinary hospitals.
How It Works
Veterinary chambers follow the same physical principles as human HBOT: pressurised oxygen (or air with oxygen delivery) elevates dissolved oxygen in the animal's plasma. Horses are led into walk-in chambers; small animals are placed in a monoplace-style unit. Sedation is sometimes used for anxious or uncooperative patients, particularly in equine HBOT.

Clinical Uses
- Equine performance recovery — tendon injury, soft-tissue strain, post-race recovery.
- Equine post-surgical convalescence — orthopaedic and soft-tissue surgery.
- Canine wound care — chronic non-healing wounds, surgical dehiscence.
- Canine acute spinal cord injury — adjunct to standard neurological care.
- Snake bite envenomation (equine, canine, feline).
- Exotic animal medicine — selected cases in zoo and wildlife veterinary practice.
Pros & Cons
Advantages
- Growing evidence base in equine performance and veterinary wound care.
- Species-specific chambers accommodate animal physiology and behaviour.
- Non-invasive adjunct to standard veterinary treatment.
Limitations
- Veterinary HBOT is less regulated than human HBOT — training and accreditation vary.
- Capital cost of equine chambers is substantial ($200K–$500K).
- Research evidence base is thinner than human HBOT.
Cost & Access
Equine chambers: $200,000–$500,000+ including facility costs. Per-session veterinary HBOT in equine racing contexts runs $100–$300 per treatment. Small-animal veterinary HBOT at specialty hospitals is typically $100–$250 per session. No insurance (veterinary insurance plans vary on HBOT coverage).

Frequently Asked Questions
Does my local vet offer HBOT?
Veterinary HBOT is available at specialty veterinary hospitals, equine performance centres, and some university veterinary schools. General practice veterinary clinics typically refer to these specialty centres.
What conditions respond to veterinary HBOT?
Equine: tendon injury, soft-tissue strain, post-surgical recovery, laminitis. Canine: chronic wounds, spinal cord injury, snake bite, post-surgical complications. Evidence varies by indication; discuss with your veterinarian.
Is veterinary HBOT safe?
With proper facility design, trained staff, and species-appropriate protocols, veterinary HBOT is safe. The main considerations are animal cooperation during pressurisation, barotrauma prevention, and standard HBOT fire safety.
