Dive time
Elapsed time between leaving the surface to descend, and
returning to the surface at the end of a dive.
EAD
Abbreviation for equivalent air depth.
EAN
Abbreviation for enriched air nitrox.
Enriched Air Nitrox Also called Nitrox or Enriched Air = EANx. Air that has
some oxygen added. Standard mixes are EAN32 (NOAA
Nitrox I = NN I) and EAN36 (NOAA Nitrox II = NN II).
Equivalent Air Depth Nitrogen partial pressure equivalent table.
Floor
The deepest depth during a decompression stop dive at which
decompression takes place.
Freediver
A breath-holding diver whose only source of oxygen are his
lungs filled with surface air.
Half-time
After a change in ambient pressure, the amount of time
required for the partial pressure of nitrogen in a theoretical
compartment to go half-way from its previous value to
saturation at the new ambient pressure.
Hypercapnia
Increased amount of carbon dioxide in the blood. A diver
who does not rest adequately between breath-hold dives will
have elevated carbon dioxide levels. This can predispose hin
to carbon dioxide toxicity or blackout.
