E EAD Equivalent Air Depth The depth at which air would cause as much decompression obligation as a nitrox with a given fO2 at a given depth. EAD = (Depth+33') fN2/0.79 - 33' = (Depth+33') (1-fO2)/0.79 - 33'
All depths in fsw .
EAN, EANx Enriched Air Nitrox
EAR Expired Air Rescusitation (preferred term now is AV in Britain)
EAV Expired Air Ventilation (British)
END Equivalent Narcotic Depth. The depth at which air would cause as much narcosis as a given mix and depth. END is typically chosen to be 99 fsw or 132 fsw for a bottom mix. Assuming that O2 and N2 are equally narcotic in practice; ignoring the narcotic potential of He (which is small, or perhaps non existent); and with depths in fsw:
END = ((1-fHe) (Depth / 33 +1)-1) * 33 = (Depth+33') (1-fHe) - 33'
Many texts have not been updated to reflect the finding that O2 and N2 are approximately equally narcotic, and instead attribute all narcosis to ppN2. This changes the formula to:
END = (( fN2/.791 ) (depth / 33 +1)-1) * 33 Obsolete
To make things worse, O2 & N2 are probably not equipotent for narcosis at all concentrations. It seems that at certain ratios, the O2 component is more narcotic than N2; and in other ratios, the N2 is more potent. See Narcosis on Wrolf's Wreck for further details.
But assuming O2 & N2 are equipotent for narcosis is the best current practice.
