Under high pressures, heliox has advantages due to a countercurrent exchange. May have advantages, you mean. Your link is to a research proposal which originated from the fact that it is simply not known if heliox has advantages. The evidence is poor or lacking, hence the proposal for a randomised controlled trial.Many experienced diving physicians feel that the Comex 30 and its variants offer no advantage over a fully-extended USN Table 6 (RN Table 62).

Your link is to a research proposal which originated from the fact that it is simply not known if heliox has advantages. The evidence is poor or lacking, hence the proposal for a randomised controlled trial. Agree fully, "May" have. The proposal has all the pros/cons listed and the rationale for its use in one site. The disagreement as apitkin puts is why such a study need be done. Typically, the Comex 30 table is considered for severe DCI. As a summary:Many experienced diving physicians feel that the Comex 30 and its variants offer no advantage over a fully-extended USN Table 6 (RN Table 62).
