The PureVent Oxygen Chamber for Large Pets is Finally Here

Large PureVent Pet Oxygen Chamber

The Large PureVent Oxygen Chamber is now available, bringing the same trusted technology and safety features of the original PureVent to pets up to 70 lbs. Designed in response to customer and veterinary feedback, it offers a spacious, comfortable environment for larger pets who need oxygen therapy at home or in the clinic. This new size ensures that bigger pets can finally breathe easy with the same quality care Pawprint Oxygen is known for.

We’re thrilled to announce the arrival of the new Large PureVent Oxygen Chamber, specially designed for pets up to 70 lbs. This long-awaited addition was created in response to feedback from veterinarians and pet parents who wanted the same trusted PureVent experience for their larger companions.


Built with the same Tri-Vent technology, safety features, and clear visibility as our standard sized chamber, the Large PureVent simply gives bigger pets the space and comfort they need to breathe easier during oxygen therapy. Now, medium and large breeds can benefit from the same advanced respiratory support trusted by veterinary teams and pet owners across the country, just in a larger size.

Why Large Pets Need Oxygen Therapy Too


Medium and large breeds can experience serious respiratory challenges that make every breath a struggle. Conditions such as pneumonia, laryngeal paralysis, or heart failure often require supplemental oxygen to help stabilize breathing and promote recovery. A controlled oxygen environment can make all the difference, ensuring safe, effective care at home under veterinary supervision.


Common reasons large pets may need oxygen therapy include:

  • Pneumonia or bronchitis causing low oxygen levels
  • Laryngeal paralysis leading to airway obstruction
  • Congestive heart failure with fluid buildup and breathing difficulty
  • Smoke inhalation or toxin exposure requiring oxygen support
  • Post-anesthesia recovery to help restore normal breathing patterns

Introducing the Large PureVent Oxygen Chamber


The Large PureVent Oxygen Chamber brings the same trusted design and performance of the standard sized PureVent to bigger pets with more room to breathe. Measuring 44” x 26” x 26”, it comfortably accommodates pets up to 70 pounds, making it ideal for medium and large breeds that need oxygen therapy. Just like the standard PureVent chamber, it offers identical features and functionality for consistent comfort and safety.


Key features include:

  • Tri-Vent technology for balanced airflow and oxygen dispersion
  • Anti-fog, transparent panels for clear monitoring
  • Easy-zip entry and reinforced structure for durability
  • Compatibility with the PureVent 10-Liter Concentrators for continuous therapy

Is the large oxygen chamber suitable for small animals, or just larger dogs?

The Large PureVent Oxygen Chamber is primarily designed for medium to large dogs up to 70 lbs., but it can safely accommodate smaller pets as well when extra space is preferred for comfort.

How does the Large PureVent maintain safe oxygen levels inside the chamber?

The Large PureVent maintains safe oxygen levels through its Venturi adapters and Tri-Vent technology, which ensures consistent airflow, proper oxygen dispersion, and continuous ventilation throughout each therapy session.

Can I adjust the oxygen concentration for my pet’s needs?

Yes, the oxygen concentration can be adjusted using Venturi adapters, allowing you to tailor the oxygen saturation to your pet’s specific therapeutic needs under veterinary guidance.

Designed for Comfort and Versatility


The Large PureVent was designed with the comfort of bigger pets in mind. Its spacious interior lets pets stretch out and relax, reducing stress during therapy sessions. Oxygen levels can be adjusted using Venturi adapters for personalized treatment, while extra room allows for bedding or familiar items to help pets feel calm. Despite its larger size, the chamber remains lightweight, foldable, and easy to assemble, whether used at home or in a clinic.

Ideal for Veterinary Clinics and Home Use


The Large PureVent performs seamlessly in both veterinary hospitals and home-care environments. In clinics, it provides a secure, controlled space for post-procedure recovery or ICU oxygen support. At home, it enables pet parents to continue veterinary-prescribed oxygen therapy for chronic respiratory conditions, offering professional-grade care in a familiar setting. Whether for short-term stabilization or ongoing treatment, the Large PureVent delivers reliability and peace of mind.
