+  algorithm, with fast tissues on the left hand side.

+- The top black horizontal line indicates the inert gas pressure limit

+Display the tissue heat-map. The heat map summarises, for the duration of

+compartments of the Bühlmann model. Blue colours mean low gas pressures in a
+tissue compartment and thus on-gassing, green to red means excess gas in the

+Image *A* on the left shows the xref:S_gas_pressure_graph[Gas Pressure
+Graph] in the *Information box*, representing a snapshot of inert gas
+pressures at a particular point in time during the dive. The inert gas
+pressures of 16 tissue compartments are shown as dark green vertical bars
+with the quick tissue compartments on the left and the slow tissue
+compartments on the right. Refer to the section on the
+xref:S_gas_pressure_graph[Gas Pressure Graph] for more details on the
+different elements of this graph.
+
+Image *B* shows a gradient of unique colours, spanning the whole range of
+inert gas pressures.  It is possible to map the height of each of the dark
+green vertical bars of *A* to a colour in *B*. For instance, the fastest
+(leftmost) dark green verical bar in *A* has a height corresponding to the
+medium green part of *B*. The height of this bar can therefore be summarised
+using a medium green colour. Similarly, the highest dark green bar in *A* is
+as high as the yellow part of *B*. The 14 remaining tissue pressure bars in
+*A* can also be translated to colours. The colours represent three ranges of
+tissue inert gas pressure:
+
+ -  The bottom range in *B* (marked _On-gassing_) includes colours from light
+    blue to black, representing tissue gas pressures below the equilibrium
+    pressure of inert gas (bottom horizontal line in *A*). The measurement unit
+    is the % of inert gas pressure, relative to the equilibrium inert gas
+    pressure. In this range on-gassing of inert gas takes place because the
+    inert gas pressure in the tissue compartment is lower than in the
+    surrounding environment. Black areas in the heat map indicate that a tissue
+    compartment has reached the equilibrium inert gas pressure, i.e. the inert
+    gas pressure in the tissue compartment equals that of the water in which the
+    diver is. The equilibrium pressure changes according to depth.
+
+ -  The central range in *B* includes the colours from black to light green,
+    when the inert gas pressure of a tissue compartment is higher than the
+    equilibrium pressure but less than the ambient pressure.  In this zone
+    decompression is not very efficient because the gradient of inert gas
+    pressure from tissue to the environment is relatively small and indicated by
+    dark green areas of the heat map.
+
+ -  The top range in *B* (marked _Off-gassing_) includes colours from light
+    green to red and white, repesenting tissue gas pressures above that of the
+    total ambient pressure (top of light green area of *A*). The measurement
+    unit is the % of inert gas pressure above ambient pressure, relative to the
+    Bühlmann M-value gradient (bottom of red area in *A*). These tissue
+    pressures are normally reached while ascending to a shallower depth.  Below
+    a value of 100%, this range indicates efficient off-gassing of inert gas
+    from the tissue compartment into the environment. Usually, efficient
+    off-gassing is indicated by light green, yellow or orange colours.  Above
+    100% (red to white in *B*) the M-value gradient is exceeded and the
+    probability of decompression sickness increases markedly.
+
+Image *C* shows the colour mapping of each of the vertical bars in *A*, the
+fast tissues (on the left in *A*) depicted at the top and the slow tissue
+compartments at the bottom of *C*. The highest vertical bar in *A* (vertical
+bar 3rd from the left) is presented as the yellow rectangle 3rd from the top
+in *C*. The 16 vertical bars in *A* are now presented as a vertical column
+of 16 coloured rectangles, representing a snapshot of tissue compartment gas
+pressures at a particular instant during the dive.
+
+Image *D* is a compilation of similar colour mappings of 16 tissue
+compartments during a 10-minute period of a dive, the colours representing
+the inert gas loading of a tissue compartment at a point in time during the
+dive. Faster tissues are shown at the top and slower tissues at the bottom,
+with time forming the horizontal axis of the graph. The column of rectangles
+in *C* can be found on the horizontal axis between 9 and 10 minutes.
+
+The colours of the heat map are not affected by the gradient factor
+settings.  This is because the heat map indicates tissue pressures relative
+to the Bühlmann M-value gradient, and not relative to any specific gradient
+factor. For more information external to this manual see:
+
+http://www.tek-dive.com/portal/upload/M-Values.pdf[Understanding M-values by
+Erik Baker, _Immersed_ Vol. 3, No. 3.]
+
+Since the colours of the heat map are not affected by the gradient
+factor(s), the heat map is also applicable when using the VPM-B
+decompression model.
+
+The image below compares the profiles and heat maps for two planned
+decompression dives to 60m: the first using the Bühlmann decompression
+model, the second using the VPM-B decompression model.  Both profiles have
+the same total decompression time, but the VPM-B model requires deeper stops
+early in the acent phase.
+
+In both profiles, the inert gas pressures in the faster tissues rise much
+more rapidly than the slower tissues during the descent and bottom phase,
+with the colors transitioning from light blue through blue and purple to
+black.  Similarly, the inert gas pressure in the fast tissues reduces more
+rapidly than the slow tissues at each decompression stop, with colors
+transitioning from red, orange and yellow to green and black.
+
+The comparison of the two profiles and heatmaps shows that by including deep
+stops, the oversaturation gradient in the faster tissues early in ascent
+phase is reduced.  However, on-gassing of slower tissues continues during
+the deep stops, which leads to greater oversaturation gradient in slower
+tissues at the end of the dive.

-

-
-- The light green area indicates the total gas, with the top margin of the
-  light green area showing the total gas pressure inhaled by the diver and
-  measured from the bottom of the graph to the top of the light green
-  area. This pressure has a _relative_ value in the graph and does not
-  indicate absolute pressure.
-
-- The horizontal black line underneath the light green margin indicates the
-  equilibrium pressure of the inert gases inhaled by the diver, usually
-  nitrogen. In the case of trimix, it is the pressures of nitrogen and helium
-  combined. In this example, the user is diving with EAN32, so the inert gas
-  pressure is 68% of the distance from the bottom of the graph to the total
-  gas pressure value.
-
-- The dark green area at the bottom of the graph represents the pressures of
-  inert gas in each of the 16 tissue compartments, following the Bühlmann
-  algorithm, the fast tissues being on the left hand side.
-
-- The top black horizontal line indicates the gradient factor that applies to
-  the depth of the diver at the particular point on the *Dive Profile*. The
-  gradient factor shown is an interpolation between the GFLow and GFHigh
-  values specified in the Graph tab of the *Preferences Panel* of
-  *Subsurface*.
-
-- The bottom margin of the red area in the graph indicates the Bühlman-derived
-  M-value. That is the pressure value of inert gases at which bubble formation
-  is expected to be severe, resulting in decompression sickness.
-
-These five values are shown on the left in the graph above. The way the Gas
-Pressure Bar Graph changes during a dive can be seen on the right hand side
-of the above figure for a diver using EAN32.
-
-- Graph *A* indicates the start of a dive with the diver at the surface. The
-  pressures in all the tissue compartments are still at the equilibrium
-  pressure because no diving has taken place.
-
-- Graph *B* indicates the situation after a descent to 30 meters. Few of the
-  tissue compartments have had time to respond to the descent, so their gas
-  pressures are far below the equilibrium gas pressure.
-
-- Graph *C* represents the pressures after 30 minutes at 30 m. The fast
-  compartments have attained equilibrium (i.e. they have reached the hight of
-  the black line indicating the equilibrium pressure). The slower compartments
-  (towards the right) have not reached equilibrium and are in the process of
-  slowly increasing in pressure.
-
-- Graph *D* shows the pressures after ascent to a depth of 4.5 meters. Since
-  during ascent the total inhaled gas pressure has decreased strongly from 4
-  bar to 1.45 bar, the pressures in the different tissue compartments now
-  exceed that of the total gas pressure and approach the gradient factor value
-  (i.e.  the top black horizontal line). Further ascent will result in
-  exceeding the gradient factor value (GFHigh), endangering the diver.
-
-- Graph *E* indicates the situation after remaining at 4.5 meters for 10
-  minutes. The fast compartments have decreased in pressure. As expected, the
-  pressures in the slow compartments have not changed much.  The pressures in
-  the fast compartments do not approach the GFHigh value any more and the
-  diver is safer than in the situation indicated in graph *D*.
