4. Before diving
Please read this manual thoroughly and understand meanings of what displayed information are and that functions before using the device.
Ensure that user has all the responsibilities for own safety. Proper use of dive computer makes itself a fine tool.
However, no dive computer can replace authorized and proper trainings include basic decompression training.
Nitrox diving may cause more risks including serious injuries and death to divers
Divers who have not acquired qualification from authorized agencies must not use mixed gases other than O2 when diving.
4.1 Buhlmann(ZH-L16C) Algorithm
CYANO uses ZH-L16C, which shows most outstanding performance among the existing algorithm.
The
Bühlmann decompression algorithm
is a mathematical model (algorithm) of the way in which inert gases enter and leave the human body as the ambient
pressure changes. Various versions, Bühlmann
created with his successors, are used to create
Bühlmann decompression tables
and to compute, in personal dive
computers, no-decompression limits and decompression schedules for dives in real-time. These decompression tables allow divers to plan the depth and duration
for dives and the required decompression stops.
The model assumes perfusion limited gas exchange and multiple parallel tissue compartments and uses an inverse exponential model for in-gassing and
out-gassing, both of which are assumed to occur in the dissolved phase (without bubble formation).
Buhlmann(ZH-L16C) especially is the 16 compartment algorithm with further modification to the middle and faster “a” values, intended for use in dive computers
as a "package". It can be used with almost all low-level processor units but it is less flexible compared to the ZHL16B.
