Description
CC and BO mode
TEMP
: Shows the current temperature in degrees Celsius.
GF:
Shows the set low and high gradient factors.
FiO2:
Shows the oxygen concentration of the breathing gas.
This value is independent of the ambient pressure!
CC and BO mode
GF99:
Shows the current M-value gradient as a percentage.
If no outgasing is taking place, ”On Gas” is displayed.
CEIL:
Indicates the upper limit of the ceiling in metres.
@+5:
Indicates the new TTS if the diver were to stop for 5 further
minutes at the current depth.
TTS:
Shows the current TTS.
CC and BO mode
The tissues bar graph shows the tissue compartment inert gas tissue
tensions based on the Bühlmann ZHL- 16C model. Note that VPM- B also
tracks tensions in the same way.
The fastest tissue compartment is shown on the top, and the slowest on
the bottom. Each bar is the combined sum of the nitrogen and helium
inert gas tensions. Pressure increases to the right.
The vertical black line shows the inert gas inspired pressure. The bound-
ary between the green and yellow zones is the ambient pressure. The
boundary between the yellow and red zone in the ZHL- 16C M- Value
pressure.
Note that the scale for each tissue compartment above the green zone
is different. The reason the bars are scaled in this way is so that the
tissues tensions can be visualized in terms of risk (i.e. how close they
are as a percentage to Bühlmann’s original super- saturation limits). Also,
this scale changes with depth, since the M- Value line also changes with
depth.
1 = 16 tissue compartments
2 = Inspired inert gas pressure
3 = Ambient pressure
4 = M-value pressure
