Hyperbaric oxygen therapy (HBOT) is no longer reserved exclusively for human patients. Over the past two decades, veterinary medicine has embraced this technology as a growing area of clinical interest, applying the same scientific principles that have made HBOT a valuable tool in human healthcare. As veterinary professionals and pet owners alike seek advanced therapeutic options for animal patients, hyperbaric oxygen therapy has emerged as a subject of increasing research and clinical application in veterinary practice.
The fundamental science behind veterinary HBOT is identical to human HBOT. By placing an animal inside a pressurized chamber and delivering concentrated oxygen, more oxygen dissolves into the blood plasma than is possible under normal atmospheric conditions. This oxygen-rich plasma can reach tissues and areas of the body that may have compromised blood flow, supporting the body's natural healing processes. The Veterinary Hyperbaric Medicine Society (VHMS) has been instrumental in advancing education, research, and clinical standards for the use of HBOT in animal patients.
Which Animals Can Receive Hyperbaric Oxygen Therapy?
One of the remarkable aspects of veterinary HBOT is its versatility across species. The therapy has been used with a wide variety of animal patients, ranging from common household pets to large animals and exotic species.
Dogs and cats represent the most commonly treated companion animals in veterinary hyperbaric medicine. Their size makes them well-suited for treatment in both portable and clinical hyperbaric chambers, and the growing body of published case reports involving canine and feline patients has contributed significantly to the veterinary HBOT knowledge base.
Horses have also been subjects of HBOT research, particularly for conditions related to wound healing and limb injuries. Equine hyperbaric therapy typically requires larger chamber configurations to accommodate the size of the animal, and several equine veterinary facilities have incorporated HBOT into their treatment offerings.
Exotic animals including birds, reptiles, ferrets, rabbits, and zoo animals have been treated with HBOT in various clinical settings. Case reports have described the use of hyperbaric therapy in a range of exotic species, and veterinary professionals continue to explore applications across the animal kingdom. The adaptability of modern hyperbaric chambers allows clinics to treat patients of varying sizes and species with appropriate modifications to protocols.
Veterinary Applications Being Studied
Research into veterinary HBOT spans a diverse range of conditions and clinical scenarios. While the evidence base is still developing compared to human applications, published case reports and studies have described outcomes across several areas of veterinary medicine.
Wound healing is one of the most extensively studied applications of veterinary HBOT. Research suggests that the increased oxygen delivery provided by HBOT may support the formation of new blood vessels (angiogenesis), enhance collagen synthesis, and promote tissue repair. Case reports have described the use of HBOT in managing surgical wound complications, traumatic wounds, bite wounds, and degloving injuries in both dogs and cats. According to a review published in the journal Veterinary Surgery, HBOT may be a useful adjunctive therapy for wounds that are slow to heal or have compromised blood supply.
Post-surgical recovery is another area where veterinary professionals have explored the use of HBOT. Case reports have described the use of hyperbaric therapy following orthopedic procedures, spinal surgeries, and other complex veterinary operations. The theory is that increased tissue oxygenation during the post-operative period may support healing and help manage swelling at the surgical site.
Snake and spider envenomation represents a particularly notable area of veterinary HBOT research. Venomous bites from snakes such as rattlesnakes, copperheads, and cottonmouths, as well as spider bites from brown recluse spiders, can cause significant tissue damage in animal patients. Case reports have described the use of HBOT as an adjunctive therapy alongside standard antivenom and supportive care, with some authors noting that HBOT may help address the tissue necrosis and vascular compromise associated with envenomation.
Smoke inhalation is an emergency condition that can affect pets caught in house fires or exposed to other smoke sources. Research suggests that HBOT may help address carbon monoxide poisoning and support oxygen delivery to tissues affected by smoke inhalation injury. Case reports in the veterinary literature have described the use of HBOT in dogs and cats following smoke exposure.
Neurological conditions including intervertebral disc disease (IVDD) and spinal cord injuries are being investigated as potential applications for veterinary HBOT. IVDD is a common and often debilitating condition in certain dog breeds, and some veterinary practitioners have explored whether HBOT, as part of a comprehensive treatment plan, may support neurological recovery. Published case reports have described outcomes in dogs with IVDD treated with HBOT as an adjunctive therapy.
Thermal burns from heat, chemicals, or electrical sources can cause extensive tissue damage in animals. Research suggests that the enhanced oxygenation provided by HBOT may support the healing process in burned tissues by promoting blood vessel formation and reducing inflammation at the wound site. Case reports have described improved outcomes in animal burn patients when HBOT was used alongside standard wound care protocols.
How Veterinary HBOT Sessions Work
Veterinary HBOT sessions share the same basic principles as human sessions, but with important animal-specific considerations that make the process well-suited for a wide range of patients. Understanding how these sessions work can help veterinary professionals and pet owners feel more comfortable with the therapy.
Unlike human patients, animals treated in hyperbaric chambers do not need to wear a mask or breathing apparatus. When the entire chamber is pressurized with oxygen, the animal simply breathes the oxygen-enriched atmosphere naturally. This is one of the significant advantages of using a whole-body chamber for animal patients, as it eliminates the stress and difficulty of fitting a mask on an animal and makes the experience more comfortable for the patient.
The transparent walls of OxyHealth chambers provide a critical advantage in veterinary applications. Veterinary staff can continuously observe the animal throughout the entire session without interrupting the pressurized environment. This allows for real-time monitoring of the patient's behavior, breathing, and comfort level. If any signs of distress are observed, the session can be adjusted or ended promptly.
Sedation is rarely needed for veterinary HBOT sessions. Most animals, particularly dogs and cats, acclimate quickly to the chamber environment. Many animals rest or sleep during their sessions once they become familiar with the routine. For patients that are initially anxious, veterinary teams may introduce the animal to the chamber gradually over one or two introductory sessions. In rare cases where an animal remains highly agitated, a mild sedative may be administered at the discretion of the veterinarian, but this is the exception rather than the rule.
A typical veterinary HBOT session follows a structured protocol: the animal is placed comfortably inside the chamber, the chamber is gradually pressurized to the target pressure (a process that takes several minutes), the animal breathes the pressurized oxygen for the prescribed treatment duration (usually 45 to 90 minutes), and then the chamber is slowly depressurized back to normal atmospheric pressure. The gradual pressurization and depressurization are important for the comfort and safety of the animal patient.
The Veterinary Hyperbaric Medicine Society
The Veterinary Hyperbaric Medicine Society (VHMS) plays an important role in advancing the field of veterinary HBOT. The organization works to promote education, research, and clinical standards for hyperbaric medicine in veterinary practice. The VHMS provides resources for veterinary professionals interested in learning about HBOT, including training programs, clinical guidelines, and a community of practitioners who share knowledge and case experiences.
The VHMS has been instrumental in establishing treatment protocols, safety standards, and best practices specifically tailored for animal patients. Their work has helped veterinary practitioners approach HBOT with a structured, evidence-informed framework, contributing to the growth and professionalization of veterinary hyperbaric medicine as a specialty area within veterinary care.

Setting Up a Veterinary HBOT Practice
Adding hyperbaric oxygen therapy to a veterinary practice requires careful planning across several areas. From facility requirements to staff training, understanding the key considerations can help practices implement HBOT successfully and safely.
Facility requirements for veterinary HBOT are relatively straightforward but important. The chamber needs to be placed in a well-ventilated room with adequate space for the chamber itself, the oxygen concentrator or oxygen supply system, and room for veterinary staff to operate the equipment and attend to patients. Electrical requirements should meet the chamber manufacturer's specifications. Fire safety considerations are also important, as hyperbaric chambers involve elevated oxygen levels. Following the manufacturer's guidelines and local fire safety regulations is essential.
Training is a critical component of establishing a veterinary HBOT practice. Veterinarians and veterinary technicians should complete training in hyperbaric medicine before offering HBOT services. The Veterinary Hyperbaric Medicine Society (VHMS) offers educational programs designed specifically for veterinary professionals. Training typically covers the physics and physiology of hyperbaric oxygen therapy, patient selection and contraindications, treatment protocols for various conditions, chamber operation and maintenance, safety procedures and emergency protocols, and documentation and record-keeping. OxyHealth provides additional training and ongoing support for practices that purchase their chambers.
Business considerations are also relevant for veterinary practices exploring HBOT. Hyperbaric therapy can serve as a valuable addition to a practice's service offerings, providing an advanced therapeutic option that may differentiate the practice in a competitive market. Practices should develop clear protocols for patient selection, informed consent, treatment documentation, and follow-up care.

Safety Considerations for Animal Patients
Safety is paramount in veterinary hyperbaric medicine, and proper attention to animal-specific considerations helps ensure positive outcomes. OxyHealth chambers are designed with multiple safety features that are particularly advantageous in veterinary settings.
Patient monitoring is facilitated by the transparent construction of OxyHealth chambers, which allows veterinary staff to observe the animal continuously throughout the session. Heart rate, respiratory rate, and behavior can be assessed visually without interrupting the pressurized environment. Some practices use additional monitoring equipment compatible with the chamber to track vital signs during sessions.
Ear and sinus considerations are important in veterinary HBOT, just as they are in human applications. The pressurization process can cause temporary discomfort in the ears if an animal has sinus congestion or ear infections. Veterinary professionals should evaluate the patient's ear and sinus health before starting HBOT and monitor for signs of discomfort during pressurization. Gradual pressure changes help minimize any ear-related discomfort.
Temperature management inside the chamber is another consideration. Pressurization can temporarily increase the temperature inside the chamber, and animals may be more sensitive to temperature changes than human patients. Monitoring the chamber temperature and ensuring adequate ventilation helps maintain a comfortable environment for the animal patient throughout the session.
Contraindications in veterinary patients are similar to those in humans. Animals with untreated pneumothorax should not undergo HBOT. Patients with certain respiratory conditions, active bleeding, or high fever may also require careful evaluation before starting hyperbaric therapy. A thorough veterinary examination before beginning any HBOT protocol is essential to identify potential contraindications and ensure the safety of the animal patient.
Fire safety protocols must be strictly followed in any setting where hyperbaric chambers are operated. Because hyperbaric environments involve elevated oxygen concentrations, all materials placed inside the chamber must be evaluated for safety. Bedding materials should be cotton or other natural fibers, and no electronic devices, metal objects, or petroleum-based products should be placed inside the chamber during a session. Veterinary staff should be trained in fire safety procedures specific to hyperbaric environments.
The Future of Veterinary Hyperbaric Medicine
Veterinary hyperbaric oxygen therapy continues to grow as a field of clinical interest and research. As more case reports are published, more veterinary professionals receive specialized training, and more practices invest in hyperbaric equipment, the body of evidence and clinical experience supporting veterinary HBOT will continue to expand.
