CONSUMER WARNING: The GSE portable chamber owned by Mad Dog Expeditions ("rental for expeditions") has an expired RINA certification (provided by the manufacturer in Italy) as of May, 2006.
Andrew Driver has been informed of this, and this portable chamber should not to be used for treatment until that certification has been reissued.
NUS, Inc.
Its never been LEGAL to use in the US... The FDA will only approve portable chambers to 4psi, and only for the treatment of acute mountain sickness.
There was another chamber being sold in the US (chamberlite), It had to be pulled otherwise the company would have lost their certification on their approved chambers.. They still might be available for sale outside of the US, but chambers for most uses fall under FDA juristration in the US.
Use of any of these chambers in areas under US juristriction may expose the operator to legal issues..
