Table 2. Venous gas emboli (VGE) grades (Eftedal-Brubakk scale) for SWEN-21 from the validation dive series ValTKLHN2021; # decompression with air (see Appendix 3 (15.4KB, pdf) for respective decompression schedules); ¤ decompression with oxygen (See Appendix 3 (15.4KB, pdf) for respective decompression schedules); a numbers of divers with cutaneous manifestation of diving not to be classified as decompression sickness (DCS), e.g., redness and pruritus; b diver who received prophylactic NBO because of arterial bubbles; HBO – hyperbaric oxygen treatment; IQR – interquartile range; min – bottom time minutes; msw – metres of seawater; NBO – normobaric oxygen treatment .
