Hyperbaric Oxygen Therapy in Nunavut

No. Nunavut has no hyperbaric facilities. Patients requiring HBOT for any of the 14 Health Canada-recognised conditions are referred south, most commonly to The Ottawa Hospital (which has established arrangements for Nunavut patients) or to Misericordia Community Hospital in Edmonton.

Out-of-territory referrals for medically necessary HBOT are coordinated through your physician and the Nunavut Department of Health. Treatment at the receiving facility is typically covered through interjurisdictional billing. The federal NIHB program may assist eligible First Nations and Inuit patients with travel and accommodation costs.

The Ottawa Hospital has long-standing arrangements to receive patients from Nunavut, particularly from the Qikiqtaaluk (Baffin) Region, given air route connections from Iqaluit to Ottawa. The hospital's hyperbaric unit treats Nunavut patients alongside Ottawa-region patients.

NIHB (Non-Insured Health Benefits) is a federal program administered by Indigenous Services Canada. It provides eligible First Nations and Inuit patients with coverage for medically necessary health-related goods and services, including travel and accommodation for out-of-territory medical care. Specific coverage and eligibility should be confirmed through NIHB and your physician.

Nunavut patients accessing HBOT through interjurisdictional referral are treated for the 14 Health Canada-recognised conditions: carbon monoxide poisoning, decompression sickness, gas or air embolism, gas gangrene, necrotising soft-tissue infections, crush injury, severe anaemia, sudden sensorineural hearing loss, problem wounds, soft-tissue radiation necrosis, radiation damage affecting bone, compromised grafts and flaps, refractory osteomyelitis, and thermal burns. Intracranial abscess (UHMS Indication #8) and central retinal artery occlusion (a sub-presentation of arterial insufficiency) are additional UHMS-listed uses treated at some Canadian hospital hyperbaric programmes, not among the named Health Canada 14.

Most chronic indications require a course of 20 to 40 daily sessions, with some radiation indications requiring up to 60 sessions. Each session typically lasts 90 to 120 minutes. Nunavut patients accessing publicly funded HBOT through interjurisdictional referral should plan for an extended stay near the receiving facility (Ottawa or Edmonton).

Call 911 or contact your local health centre. The receiving emergency department coordinates urgent air ambulance transfer to The Ottawa Hospital or Misericordia Community Hospital in Edmonton through the Nunavut Department of Health's medical transport system. Multi-leg transfers from remote communities to hub airports to receiving facilities are common. For diving emergencies, the Divers Alert Network (DAN) hotline at 1-919-684-9111 can advise on the nearest active recompression chamber.

Nunavut does not currently have an in-province hospital hyperbaric programme. Patients with one of the 14 Health Canada-recognised conditions and a physician referral are referred interprovincially to The Ottawa Hospital or Misericordia Edmonton. The referring physician initiates the out-of-province transfer through the provincial health plan's medical-travel program. Emergency cases (carbon monoxide poisoning, decompression sickness, gas embolism) are routed via provincial emergency-transport networks. Private self-pay treatment is also available at clinics in Nunavut or in neighbouring provinces; private clinic costs are typically $150 to $400 per session.

A standard HBOT session at hospital programmes and private clinics across Nunavut lasts 90 to 120 minutes door-to-door: roughly 10 to 15 minutes for compression to treatment depth, 60 to 90 minutes at treatment pressure (typically 2.0 to 2.8 ATA), and 10 to 15 minutes for decompression. Emergency indications such as carbon monoxide poisoning, decompression sickness, or air embolism may use shorter or longer protocols (typically 2 to 5 hours per session for severe cases). Most chronic-condition courses run 20 to 40 sessions delivered daily or near-daily over 4 to 8 weeks.

Private HBOT clinics in nearby provinces typically quote $150 to $400 per session for self-pay treatment, with a full 20 to 40 session course totalling approximately $3,000 to $16,000. Nunavut does not have an in-province hospital programme, but publicly funded patients with recognised indications and a physician referral are routed to The Ottawa Hospital or Misericordia Edmonton at no out-of-pocket cost via the provincial medical-travel program.

Hyperbaric oxygen therapy is generally safe when delivered in a Health Canada-licensed clinical-grade chamber under physician supervision. The most common side effects are temporary: middle-ear barotrauma during compression (managed by ear-clearing techniques), transient short-sightedness over long courses that reverses within weeks of finishing, and occasional sinus pressure. Rare serious risks include oxygen toxicity seizures (under 1 in 10,000 sessions at clinical pressures) and chamber-related pneumothorax expansion. Absolute contraindications are untreated pneumothorax, concurrent bleomycin chemotherapy, and concurrent disulfiram. Hospital programmes and CPSA-accredited private clinics follow detailed pre-treatment screening protocols.

Clinical-grade hyperbaric oxygen therapy delivers 100 per cent oxygen at 2.0 to 2.8 ATA inside a Health Canada-licensed chamber. "Mild" or "soft" hyperbaric chambers operate at 1.3 ATA or less, sometimes with ambient air rather than concentrated oxygen, and are not Health Canada-licensed for the 14 recognised indications. The clinical evidence base supporting HBOT specifically references pressures of 2.0 ATA and above; lower-pressure protocols do not produce the same dissolved-oxygen physiology. Nunavut Health Care Plan and other provincial health plans cover treatment only at hospital programmes operating clinical-grade chambers.
