How funding provided for the provision, maintenance and use of hyperbaric chambers is agreed and what this covers.

National Services Division commissions the National Hyperbaric Medicine Unit in Aberdeen Royal Infirmary as a nationally designated service to provide and co-ordinate emergency treatment and advice in Scotland for diving related illness. The national service also operates the Hyperbaric National Registration Service which recognises chambers that meet specific criteria to treat patients with Diving Decompression Illness on an emergency basis. Chambers need to apply to be part of the National Registration Service. The Hyperbaric National Registration Service currently recognises three independent chambers in Scotland, based in Orkney, Oban and Millport.
The Aberdeen service receives nationally designated funding (top sliced from NHS boards based on the NHSScotland Resource Allocation Committee (NRAC) formula). The three independent chambers invoice each NHS board for treatment of divers with diving related illness on a cost per case basis but also receive funding from public organisations to support their infrastructure as set out in the answer to question S4W-02086 on 30 August 2011.
