With a home hyperbaric unit you do not need to buy oxygen, you purchase an oxygen concentrator specifically for use with a hyperbaric chamber and it will take the air from the room and concentrate it to about 93 - 96% oxygen, you breathe this concentrated air through a mask.
To purchase a hyperbaric unit, concentrator, connectors, masks, frame, everything you need to get going it will cost about $9000 US, to bring it into Canada with duty, exchange, and GST it would be just over $10,000. Unfortunately there are no guarantees that it will do the job, so the best bet is to go to a clinic and do some sessions to see if it will benefit you before investing in a chamber. In Canada we payed around $100 per session, from what I understand it's over double that in the US, In Alberta it MAY be covered by medical (depending on your Dr.), but because Crohn's is considered an off label use it is not covered by insurance. We were able to claim our expenses back on our income tax though.
Because we had such good success with it last fall, the Dr's I have spoken with are suggesting that our son is a good candidate to be maintained with Hyperbaric, and really the chamber is supposed to last about 15 years, $10,000 is not that big of a price to pay if it works. If not, I guess we can always sell it on E-bay or Craigslist, they are becoming very popular for families with autistic members.
We have decided to go ahead and purchase one - this has not been a quick decision for us, we have been tossing it around for the last 6 months or so. If anyone is interested I can post every once in a while and let you know how our son is doing.
ozonehole, I had to laugh at building your own - my dad is a retired dairy farmer with an old steel milk tank that he's always trying to figure out how to convert into a hyperbaric unit!!
Crazyharry, I'm quite sure insurance won't cover it, we are working with a Dr. just outside of San Francisco, he seems very knowledgeable - if you want his info I can pm it to you. Also Dr. Paul Harch's office in New Orleans had lots of information for me, he was an ER Dr. and now focuses just on hyperbaric, and has a clinic, has written a book, etc.
