About Simcoe Hyperbarics: Barrie Hyperbaric Medicine
Welcome to Simcoe Hyperbarics. We provide physician-directed, medical-grade hyperbaric oxygen therapy and evidence-based care for patients across Barrie, Simcoe County, and Central Ontario.
Our Mission: Physician-Led Healing
At Simcoe Hyperbarics, our objective is to provide accessible, evidence-based hyperbaric medicine that is professional and patient-centered. As a physician-directed clinic, we deliver hospital-grade protocols in a supportive outpatient setting.
Our facility is designed to adhere to Canadian CSA standards for hyperbaric facilities and rigorous clinical protocols in Barrie and Simcoe County.

Specialized Treatment Areas
We focus on the 15 Undersea and Hyperbaric Medical Society (UHMS) approved indications, with specialized expertise in:
Idiopathic Sudden Sensorineural Hearing Loss (ISSHL)
A specialized approach to restore hearing by delivering high-pressure oxygen to inner ear tissues, reducing swelling and supporting recovery from sudden hearing loss.
Compromised Skin Grafts & Flaps
Enhances the survival of failing skin grafts and tissue flaps by stimulating new blood vessel growth and improving circulation to the affected area.
Chronic Wounds and Diabetic Ulcers
Clinical care for chronic, non-healing wounds, such as diabetic foot ulcers, utilizing oxygen to support infection control and tissue repair.
Delayed Radiation Tissue Injury & Radionecrosis
Alleviates long-term side effects of radiation therapy by promoting the regeneration of healthy blood vessels and connective tissue in damaged areas.
Chronic Refractory Osteomyelitis (CROM)
An adjunctive therapy for chronic bone infections, supporting antibiotic efficacy and bone healing in refractory cases.
Early to Mid Stage Avascular Necrosis
Helps restore blood supply to oxygen-starved bone tissue, reducing pain and potentially delaying the need for joint replacement surgery.
Crohn's Disease - Perianal & Cutaneous Fistulas
Adjunctive hyperbaric oxygen therapy for medically refractory perianal and cutaneous fistulizing Crohn's disease.
Benefits of HBOT
Hyperbaric Oxygen Therapy delivers 100% oxygen at increased atmospheric pressure, triggering several vital physiological responses.
Enhanced Wound Healing
Stimulates the growth of new blood vessels (angiogenesis) and collagen production in chronic, non-healing wounds.
Reduced Inflammation
Documented anti-inflammatory effects that help reduce edema and swelling in acute injuries and chronic conditions.
Infection Control
Increases the body's ability to fight certain types of bacteria and enhances the effectiveness of some antibiotics.
Tissue Salvage
Provides critical oxygen to tissues threatened by ischemia, such as compromised skin grafts or flaps.
