Decompression sickness
Any of a variety of maladies resulting either
primarily or secondary from the formation of
nitrogen bubbles in tissues or body fl uids, as a result
of inadequately controlled decompression.
Commonly called “bends” or “DCS”.
Dive series A group of repetitive dives between which the dive
computer indicates some nitrogen loading is
present. When nitrogen loading reaches zero the
dive computer deactivates.
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 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 dive at
which decompression takes place.
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.
Multi-level dive A single or repetitive dive that includes time spent
at various depths and whose no-decompression limits
are not determined solely by the maximum depth
attained.
NITROX Any nitrogen-oxygen mix including standard air.
NOAA United States National Oceanic and Atmospheric
Administration.
No-decompression time The maximum amount of time a diver may remain at
a particular depth without having to make
decompression stops or remain below a ceiling
during the subsequent ascent.
