Suunto Vyper Air — diving Terms: Decompression Time, Nitrox & Oxygen Toxicity Explained [62/65]
Превью страниц
Страница 62 /
65
NO DEC TIME
Abbreviation for no decompression time limit.
OEA = EAN = EANx
Abbreviations for oxygen enriched air nitrox.
OLF
Abbreviation for oxygen limit fraction.
OTU
Abbreviation for oxygen tolerance unit.
Oxygen tolerance unit
Used to measure the whole-body-toxicity.
Oxygen limit fraction
A term used by Suunto for the values displayed in the oxygen toxicity bar graph.
The value is either the CNS% or the OTU%.
O
2
%
Oxygen percentage or oxygen fraction in the breathing gas. Standard air has
21% oxygen.
Oxygen partial pressure
Limits the maximum depth to which the nitrox mixture can be safely used.The
maximum partial pressure limit for enriched air diving is 1.4 bar.The contingency
partial pressure limit is 1.6 bar. Dives beyond this limit risk immediate oxygen
toxicity.
PO
2
Abbreviation for oxygen partial pressure.
RGBM
Abbreviation for Reduced Gradient Bubble Model.
Reduced Gradient Bubble Model
Modern algorithm for tracking both dissolved and free gas in divers.
Repetitive dive
Any dive whose decompression time limits are affected by residual nitrogen
absorbed during previous dives.
Residual nitrogen
The amount of excess nitrogen remaining in a diver after one or more dives.
SURF TIME
Abbreviation for surface interval time.
Surface interval time
Elapsed time between surfacing from a dive and beginning a descent for the
subsequent repetitive dive.
Tissue group
Theoretical concept used to model bodily tissues for the construction of
decompression tables or calculations.
Whole-body toxicity
Another form of oxygen toxicity, which is caused by prolonged exposure to
high oxygen partial pressures. The most common symptoms are irritation in
the lungs, a burning sensation in the chest, coughing and reduction of the vital
capacity. Also called Pulmonary Oxygen Toxicity. See also OTU.

- If the calibration fails several times in a row it is possible that you are in an area with sources of magnetism such as large metal objects power lines or electric appliances move to another location and try to calibrate the compass again if the calibration continues to fail contact an authorized suunto service center p.15
- Declination you can compensate for the difference between true north and magnetic north by adjusting the compass declination the declination can be found for example from sea charts or topographic maps of the local area p.15
