The aim of this study is to see weather hyperbaric oxygen treatment is beneficial as adjuvant
treatment for frost damage.

The investigators hope to include at least 20 patients in a randomized manner. Half of the
patients are randomized to hyperbaric oxygen, and half of the patients are randomized not to
have hyperbaric oxygen treatment.

Under hypotheses: The number og surgeries is reduced by hyperbaric oxygen treatment as
adjuvant treatment for frost damage. The functional level of the frost damaged patient is
better after 6 and 12 months when also treated with hyperbaric oxygen treatment for frost
damage.
