Talk:Equivalent narcotic depth

Page creation

This page was created to distinguish between two uses of "Equivalent air depth" in diving. The original page now contains the information and references about calculating the EAD in order to use air tables with a nitrox mix. This page contains the information and reference concerning the calculation of the Equivalent Narcotic Depth (END) for trimix (some agencies have referred to this as "EAD" in the past). The history and talk pages for the original article are here: History and Talk. --RexxS (talk) 19:28, 1 November 2008 (UTC)

Wrong abbreviation and acceptation of END

The abbreviation END say "Equivalent Nitrogen Depth" not "Equivalent Narcotic Depth". — Preceding unsigned comment added by 212.202.157.154 (talk) 10:20, 24 August 2011 (UTC)

We stopped using "Equivalent Nitrogen Depth" about 15 years ago, as it is an utterly worthless concept, because only helium has no narcotic effect. You really need to read some up-to-date sources. --RexxS (talk) 23:51, 24 August 2011 (UTC)
