Hyperbaric Oxygen Therapy for Embolisms

Mechanism

Why hyperbaric oxygen for embolisms

Arterial gas embolism is a medical emergency in which gas bubbles block blood flow, most often following diving accidents or certain medical procedures. HBOT is the definitive treatment: increased pressure physically shrinks the bubbles while elevated oxygen supports the oxygen-starved tissue downstream until circulation is restored.

Evidence

Coverage and what to expect

• It is an approved indication. OHIP covers HBOT for this condition when your physician confirms it meets the approved criteria.
• It works alongside your other treatment. HBOT supports, rather than replaces, the surgical, antibiotic, or medical care your physician is already providing.
• A physician referral is required. There is no option to self-refer or pay privately for this therapy; your physician initiates the process.
• Outcomes depend on timing and severity. How early treatment starts and the severity of the condition both affect what you can expect.

Your physician confirms whether your condition qualifies for one of the 14 OHIP-approved indications before treatment begins.

Process

What to expect

1. 1
   Referral and assessment.

   Your physician sends a referral. We review it, confirm OHIP coverage for your indication, and book your intake assessment.

2. 2
   Treatment sessions.

   Most treatments are 90 minutes of oxygen, about 2 hours in total. You rest comfortably in the chamber. Many patients listen to music, watch TV, or nap. You may feel pressure in your ears, similar to a plane landing.

3. 3
   Physician reporting.

   We monitor your progress throughout the course and report outcomes back to your referring physician.
