Elapsed Dive Time - The total time spent underwater during a dive between 5 FT (1.5 M) on initial descent to 2 FT
(0.6 M) on final ascent.
FO2 - The fraction (percent / 100) of oxygen (O2) in the breathing gas mixture.
Graphic Diver Interface ™ - Feature of AERIS dive computers that indicate the diver's status (bar graphics, icons,
graphic displays).
Icon - a small pictorial representation of an operational mode or information.
Integrated Dive Computer - A dive computer that monitors and displays cylinder pressure in addition to no decom-
pression information.
LCD - Abbreviation for liquid crystal display, an easily viewed low voltage display usually found on dive computers
Maximum Depth
- The deepest depth attained during a dive.
Mode - A specific set of functions in a dive computer.
Multi-level Dive - A type of dive profile where the diver spends various times at different depths (opposite of a “Square
Wave” dive profile).
NDC - An AERIS abbreviation for No Decompression Dive Time Remaining.
Nitrogen Loading Bar Graph
- A graphic display of simulated nitrogen absorption on AERIS dive computers.
NIBG - An AERIS abbreviation for Tissue Loading Bar Graph
Nitrox - A nitrogen-oxygen breathing gas mixture that contains a higher fraction of oxygen than air.
Nitrox Dive - A dive conducted using nitrox (22 to 99% O2) as the breathing gas.
No Deco Time Remaining - The amount of dive time remaining based on no decompression status.
No Decompression
(No Deco) - Any part of a dive where the diver can surface without requiring a decompression
stop.
O2 Bar Graph - A visual representation of oxygen accumulation on a dive computer display.
O2BG - An AERIS abbreviation for O2 Bar Graph.
OTR - An AERIS abbreviation for O2 Time Remaining.
OTU
- Abbreviation for oxygen tolerance unit. A Hamilton's Repex method term for oxygen dose.
Out of Range - The point at which a dive computer can no longer supply correct dive information.
Oxygen Tolerance - Dose or exposure to the physiological affects of elevated levels of oxygen.
Oxygen Toxicity - The adverse physiological affects of exposure to elevated levels of oxygen.
