The Isle of Man Hyperbaric Medical Facility has been operated by the Kevin Gray Memorial Trust since 1984, when a single hyperbaric chamber was donated following the death of commercial diver Kevin Gray, in whose honour the Kevin Gray Memorial Trust was founded.

In 1992, a purpose-built unit was opened on the site of the original facility behind Douglas Fire Station. The unit has two multiplace chambers with equipment for the provision of intensive care, utilising mixed gases and saturation treatments.

2010 saw the founding of fundraising body "Friends of the Hyperbaric Chamber" which is committed to raising funds to keep this vital facility open for the benefit of the Isle of Man.
