Hyperbaric Oxygen Therapy Chamber

HBOT is administering oxygen at a higher than normal atmospheric pressure. Unlike the room air we breathe (21% oxygen), HBOT delivers 100% oxygen. Each session in the HBOT chamber is called a “dive.”

Our trained medical staff closely monitors your pet during the session. Most HBOT sessions take approximately 100 minutes (20 minutes to bring to pressure, 60 minutes of “dive,” and 20 minutes to bring the pressure down). Pets that are candidates for HBOT are dived twice daily, with minimal to no sedation needed after the first two dives.

The goal of HBOT is to increase partial pressure of oxygen in the tissues of the body, which in turn increases the oxygen transport capacity of blood. Under normal atmospheric pressure, oxygen transport is limited to the oxygen binding capacity of hemoglobin in the red blood cells and the small amount transported in the blood plasma. Hemoglobin of the red blood cells is normally saturated to capacity with oxygen under normal atmospheric pressure, therefore cannot be increased even through HBOT. However, HBOT drastically increases the oxygen transported in the plasma, making oxygen available to areas normally deprived of oxygen.

HBOT can be used for various ailments and is the only known cure for severe Carbon Monoxide poisoning. Below are some of the other indications for HBOT:

  • Serious to severe wounds and/or burns

    • Dog bites

    • Rattlesnake bites

    • Radiation

  • Necrotizing soft tissue infections

  • Spinal cord injuries

  • Post-surgical

  • Inflammatory bowel disease

  • Pancreatitis

Once you have consulted with your primary care veterinarian and they have referred your pet to our specialist, you will need to book an appointment through our homepage by selecting "Book Appointment."  This is found in the upper right-hand corner of the homepage.


For the safety of all hospital patients, all dogs and cats must be leashed, crated, or carried at all times. Retractable leashes must be locked at all times. Appointments/consultations are approximately 30-60 minutes, depending on the severity of the case.
