7. GLOSSARY
AVG:  Average  depth,  calculated  from the  beginning  of  the  dive  or  from  the 
time of reset.
CNS O
2
:  Central Nervous System oxygen toxicity. 
DESAT: Desaturation time. The time needed for the body to completely eliminate 
any nitrogen taken up during diving.
Dive time: The time spent below a depth of 0.8m/3ft.
Gas 1, Gas d: Refers to the main gas (1) and the decompression gas (d) when using 
the multi gas option of the ZH-L8 ADT MB PMG algorithm.
Local time: the time in the local time zone.
Max depth: Maximum depth attained during the dive. 
MB: Microbubble. Microbubbles are tiny bubbles that can build up in a 
diver’s body during and after a dive.
MB level: One of the six steps, or levels, in SCUBAPRO’s customizable algorithm. 
MOD: Maximum Operating Depth. This is the depth at which the partial 
pressure of oxygen (ppO
2
) reaches the maximum allowed level 
(ppO
2
max). Diving deeper than the MOD will expose the diver to unsafe 
ppO
2
 levels. 
Multi gas: Refers to a dive in which more than one breathing gas is used (air and/
or Nitrox).
Nitrox: 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.
NO FLY: Minimum amount of time the diver should wait before taking a plane.
No-stop time: 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.
O
2
: Oxygen.
%O
2
: Oxygen concentration used by the dive computer in all calculations.
PDIS: Profile Dependent Intermediate Stop is an additional deep stop which 
is suggested by Meridian at depth where 3rd, 4th or 5th compartment 
starts off gassing.
PMG: Predictive Multi Gas, refers to the algorithm capable of including up to 
two different Nitrox mixes in its decompression calculations.
ppO
2
: 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
2
 higher than 1.6bar is considered dangerous.
ppO
2
max: The maximum allowed value for ppO
2
. Together with the oxygen 
concentration it defines the MOD.
Press: The act of pressing and releasing one of the buttons.
