Veterinary Hyperbaric Oxygen Therapy
Hyperbaric Oxygen Therapy (HBOT) is an advanced, non-invasive treatment that supports healing, reduces inflammation, and enhances recovery across a range of acute and chronic conditions.
HBOT has been used extensively in human medicine for decades and is now emerging as a valuable tool in veterinary care, particularly in integrative and regenerative medicine settings.
What Is Veterinary HBOT?
HBOT involves placing your pet in a specialised chamber where they breathe 100% oxygen at increased atmospheric pressure (typically around 2 atmospheres, similar to being 10 metres underwater).
Under these conditions, oxygen dissolves directly into the blood plasma, allowing it to reach tissues that are inflamed, damaged, or poorly supplied with blood.
How Does HBOT Work?
HBOT enhances the bodyβs natural healing processes through multiple mechanisms:
Increases tissue oxygenation β oxygen delivery can increase up to 10β15Γ normal levels
Improves oxygen pe*******on β reaches 3β4Γ deeper into tissues than usual
Reduces inflammation β downregulates inflammatory cytokines
Enhances immune function β improves bacterial killing by immune cells
Stimulates new blood vessel formation (angiogenesis)
Mobilises stem cells β supporting tissue repair and regeneration
Reduces swelling (oedema)
When Might HBOT Be Considered?
HBOT may be used as part of a broader treatment plan for:
Post-surgical recovery and wound healing
Neurological conditions (e.g. IVDD, spinal injury, brain injury)
Cancer support (adjunctive to chemotherapy or radiation)
Pancreatitis and inflammatory conditions
Liver disease
Cardiovascular compromise or reperfusion injury
Cognitive dysfunction and ageing support
Chronic infections or non-healing wounds
Severe inflammation (e.g. IBD, peritonitis)
It is not a standalone cure, but an adjunctive therapy designed to enhance recovery and support other treatments.
What to Expect During Treatment
HBOT is a calm, well-tolerated procedure:
Your pet is placed in a comfortable, monitored chamber
No masks or tubes are required
Gradual pressurisation (~10 minutes)
~30 minutes at therapeutic pressure
Gradual decompression (~10 minutes)
Total session time: approximately 60 minutes
Most pets relax or sleep during treatment.
At our clinic, HBOT is offered every second Friday afternoon.
Treatment Course
The number of sessions depends on the condition:
Acute conditions: typically 3β5 sessions initially
Chronic conditions: may require 3β20+ sessions
Cancer support: individualised alongside treatment protocols
Healthy ageing: periodic maintenance sessions
We generally recommend starting with a short course and adjusting based on response.
Is HBOT Safe?
HBOT is considered a very safe therapy when appropriately screened and monitored.
Large veterinary datasets show low rates of adverse events
Minor effects (e.g. restlessness) are uncommon
Rare seizures (~0.7%) resolve with decompression and have no lasting effects
All patients are assessed prior to treatment to ensure suitability.
After Treatment
Most pets tolerate HBOT well. Some may appear slightly tired initially, while others show increased energy and comfort over the following days.
