12:00 AM to 12:00 AM.


We provide hyperbaric recompression or Hyperbaric Oxygen Therapy (HBOT) to people with the below acute and elective conditions as well as providing transcutaneous studies as a supporting service.

Acute conditions that we are able to treat: 

Elective conditions that can be treated:


There are many commonly asked -about conditions for which the safety and effectiveness of HBOT has not been established.  For that reason we do not treat any of the following conditions at this unit.

  • Alzheimer's disease
  • Asthma
  • Autism
  • Bell's palsy
  • Brain injury
  • Cancer
  • Cerebral Palsy
  • Chronic Fatigue Syndrome
  • Depression
  • Fibromyalgia
  • Heart disease
  • Hepatitis
  • Migraine
  • Multiple sclerosis
  • Parkinson's disease
  • Spinal cord injury (other than DCS)
  • Sports injuries
  • Stroke

Prospective patients should also be aware that there is no reliable clinical evidence of the effectiveness of 'mild' HBOT provided by 'soft shell' chambers that can only attain pressures of up to 1.5 atmospheres.  We therefore endorse the position statement by the Undersea and Hyperbaric Medical Society (UHMS).  See attachment in our Document Download section

(see attachments here)

The Chamber
