Oxygen therapy is a critical tool in veterinary medicine, used in emergencies, post-surgical recovery, and increasingly in the form of hyperbaric oxygen therapy (HBOT) for chronic conditions in dogs, cats, horses, and other animals. Whether your pet is gasping after a near-drowning, recovering from spinal surgery, or fighting a stubborn wound infection, supplemental oxygen can be the difference between life and death.
Veterinary oxygen therapy works on the same principle as human oxygen therapy: delivering higher concentrations of oxygen than what is available in ambient air (21%) to support tissue healing, fight infection, and maintain vital organ function.
Key Takeaways
- Emergency oxygen therapy is standard of care in veterinary critical care units
- Delivery methods include oxygen cages, flow-by, nasal cannula, and masks
- Veterinary HBOT is a growing field with over 2,792 treatment sessions documented in one study
- HBOT costs -600 per session for pets; emergency oxygen is part of hospital fees
- Conditions treated range from respiratory emergencies to neurological injuries and chronic wounds
Emergency Oxygen Therapy for Pets
When a pet arrives at an emergency veterinary hospital in respiratory distress, supplemental oxygen is often the first treatment administered. Common emergency scenarios include:
- Trauma: Hit by car, falls, bite wounds with lung damage
- Respiratory distress: Asthma attacks, pneumonia, pleural effusion
- Heart failure: Congestive heart failure causing pulmonary edema
- Poisoning: Carbon monoxide exposure, smoke inhalation
- Near-drowning
- Severe anemia
- Post-surgical recovery: Especially after thoracic or upper airway surgery
How Oxygen Is Delivered to Animals
| Method | How It Works | Best For | Pros / Cons |
|---|---|---|---|
| Oxygen Cage | Enclosed chamber with controlled O2 concentration | Cats, small dogs, anxious animals | Low stress; limited access to patient |
| Flow-by Oxygen | Oxygen tubing held near the pet’s nose/mouth | Immediate stabilization, panicked patients | Quick; low concentration delivered |
| Nasal Cannula | Thin tube placed in one or both nostrils | Longer-term supplementation | Efficient; requires patient tolerance |
| Oxygen Mask | Mask fitted over muzzle | Short-term, anesthesia recovery | Higher concentration; may stress some pets |
| Intubation | Tube placed directly in trachea | Unconscious/anesthetized patients | Most reliable; invasive |
| Oxygen Hood/Collar | Elizabethan collar covered with plastic wrap + O2 line | Creative ICU solution | Improvised; effective in a pinch |
Hyperbaric Oxygen Therapy (HBOT) for Animals
Veterinary HBOT is a rapidly growing field. The treatment places animals in a pressurized chamber filled with 100% oxygen at 1.5 to 3 times normal atmospheric pressure. This dissolves 15-20 times more oxygen into the bloodstream than normal breathing.
What HBOT Treats in Animals
A retrospective analysis of 2,792 HBOT treatment sessions at veterinary facilities documented the following breakdown of conditions treated:
- Neurologic injuries: 50.4% (spinal cord injuries, intervertebral disc disease, brain trauma)
- Tissue healing: 31.4% (chronic wounds, surgical sites, burns, skin grafts)
- Oomycete infections: 5.5% (pythiosis and other fungal-like infections)
- Cancer/radiation injury: 5.4% (post-radiation tissue damage)
- Miscellaneous: 7.4% (envenomation, pancreatitis, sepsis)
“The strongest evidence in veterinary medicine is for improved wound healing, overcoming difficult-to-manage infections, vascular compromise, and soft tissue injury.”

What to Expect During a Veterinary HBOT Session
The HBOT chamber for animals resembles a large, round kennel with portholes for visibility. Sessions typically last 45-90 minutes. Most animals do not require sedation or anesthesia. Dogs and cats generally acclimate quickly to the chamber environment.
Treatment plans typically involve:
- Acute conditions: Daily sessions for 3-5 days
- Chronic wounds: 3-5 sessions per week for 2-4 weeks
- Post-surgical: 3-5 sessions starting within 24-48 hours of surgery
- Total sessions: 5-20 depending on the condition
Cost of Veterinary Oxygen Therapy
| Service | Cost Range | Notes |
|---|---|---|
| Emergency oxygen (ER visit) | -500 (part of ER fee) | Included in critical care charges |
| Oxygen cage hospitalization | -2,000/day | ICU-level care |
| HBOT per session | -600 | Most clinics charge -200/session |
| HBOT treatment plan (5-20 sessions) | -12,000 | Package discounts often available |
| Home oxygen concentrator | -800 (purchase) | For chronic conditions; vet guidance required |
Home Oxygen for Pets
For pets with chronic respiratory conditions (congestive heart failure, chronic bronchitis, laryngeal paralysis), home oxygen therapy is an option. Pet oxygen concentrators like the PureVent 5-liter model provide a continuous flow of concentrated oxygen. Owners can set up an oxygen-enriched space using an oxygen cage, tent, or even a modified crate.
Home oxygen therapy should always be set up under veterinary guidance. The vet will determine the appropriate flow rate, duration, and monitoring schedule.
Finding a Vet Clinic with Oxygen Capabilities
Standard oxygen therapy (cages, flow-by, nasal cannula) is available at virtually all emergency veterinary hospitals and most specialty practices. HBOT is more specialized. As of 2026, veterinary HBOT is available at select specialty hospitals and rehabilitation centers across the United States, with availability growing.
To find a clinic offering veterinary HBOT:
- Ask your primary veterinarian for a referral
- Contact veterinary specialty hospitals in your area
- Search for “veterinary hyperbaric oxygen therapy” plus your city or state
- University veterinary hospitals (e.g., University of Florida College of Veterinary Medicine) often have HBOT capabilities
The Bottom Line
Oxygen therapy is an established and essential part of veterinary medicine. Emergency oxygen saves lives every day in veterinary ERs. HBOT is a newer addition with growing evidence, particularly for neurologic injuries and chronic wounds. While HBOT is not available everywhere and can be expensive, it offers a non-invasive option for conditions that may not respond to conventional treatment alone.
If your pet has a chronic condition that might benefit from oxygen therapy, talk to your veterinarian about whether supplemental oxygen or HBOT could be part of the treatment plan.
