LUNA 2.0 AI USER MANUAL
Average depth, calculated from the beginning of the dive or from the time of reset
Central Nervous System oxygen toxicity
Desaturation time. The time needed for the body to completely eliminate any nitrogen taken
up during diving
The time spent below a depth of 0.8m/3ft
Refers to the main gas that is set for the ZH-L16 ADT MB PMG or ZH-L16C+GF PMG
algorithm
Gradient Factor. Gradient factors are a way to introduce conservatism to the base
algorithm and they are expressed in % values in format low/high
Surface interval, the time from the moment the dive is closed out
Maximum depth attained during the dive
Microbubbles: Microbubbles are tiny bubbles that can build up in a diver's body during and
after a dive
One of the 6 steps, or levels (L0 to L5), in SCUBAPRO's customizable algorithm
Maximum Operating Depth. This is the depth at which the partial pressure of oxygen
(ppO ) reaches the maximum allowed level (ppO

expose the diver to unsafe ppO
A breathing mix made of oxygen and nitrogen, with the oxygen concentration being 22%
or higher. In this manual, air is considered as a particular type of nitrox
Minimum amount of time the diver should wait before performing another dive
Minimum amount of time the diver should wait before taking a plane or ascending to
altitudes higher than 2000m/6562ft
This is the time that a diver can stay at the current depth and still make a direct ascent to
the surface without having to perform decompression stops
Oxygen
Oxygen concentration used by the computer in all calculations
Profile Dependent Intermediate Stop is an additional deep stop which is suggested by the
dive computer at a depth where the 5th, 6th or 7th compartment starts off-gassing
Predictive Multi-Gas. It lets you carry additional breathing gases in addition to your main
breathing gas
Partial pressure of oxygen. This is the pressure of the oxygen in the breathing mix. It is
a function of depth and oxygen concentration. A ppO

Remaining Bottom Time. The time you can spend at the current depth and still have
enough gas supply to make a safe ascent and reach the surface with the tank reserve
Oxygen Toxicity Unit. It is the degree of pulmonary oxygen toxicity produced by breathing
100% O continuously at a pressure of 1 atmosphere absolute (ATA) for 1 minute

The result of having completed a dive without respecting all mandatory decompression
obligations
Surface interval. The time that starts at the moment the dive is closed out
The depth at which the diver plans to switch to a higher oxygen concentration mix while
using the multi-gas option
Total Ascent Time. It is the time it should take the diver to get to the surface from their
present depth
