DCI Abbreviation for decompression illness.
Decompression Time spent at a decompression stop or range before surfacing,
to allow absorbed nitrogen to escape naturally from tissues.
Decompression range
On a decompression stop dive the depth range, between the
floor and ceiling, within which a diver must stop for some
time before surfacing.
Decompression illness
Any of a variety of maladies resulting either directly or
indirectly from the formation of nitrogen bubbles in tissues
or body fluids, as a result of inadequately controlled
decompression. Commonly called "bends" or "DCI".
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.
