Suunto VYTEC DS manual Suunto Reduced Gradient Bubble Model Rgbm, Surface Intervals

Page 68

Before high altitude diving, the instrument must be set to the Altitude Adjustment mode to adjust the calculations for the new altitude. The maximum partial pressures of nitrogen allowed by the mathematical model of the dive computer are reduced according to the lower ambient pressure.

As a result, the allowed no-decompression stop limits are considerably reduced.

SURFACE INTERVALS

The dive computer requires a minimum surface interval of 5 minutes between dives. If a surface interval is shorter than 5 minutes, the next dive is treated as a continuation of the previous dive.

6.2.SUUNTO REDUCED GRADIENT BUBBLE MODEL (RGBM)

The Suunto Reduced Gradient Bubble Model (RGBM) is a modern algo- rithm for predicting both dissolved and free gas in the tissues and blood of divers. It was developed in a co-operation between Suunto and Bruce R. Wienke BSc, MSc. PhD. It is based on both laboratory experiments and diving data, including data from DAN.

It is a significant advance on the classical Haldane models, which do not predict free gas (microbubbles). The advantage of Suunto RGBM is ad- ditional safety through its ability to adapt to a wide variety of situations. Suunto RGBM addresses a number of diving circumstances outside the range of just dissolved gas models by:

Monitoring continuous multiday diving

Computing closely spaced repetitive diving

Reacting to a dive deeper than the previous dive

Adapting for rapid ascents which produce high micro-bubble (silent-bubble) build-up

Incorporating consistency with real physical laws for gas kinetics.

Suunto RGBM Adaptive decompression

The SUUNTO RGBM algorithm adapts its predictions of both the effects of micro-bubble build-up and adverse dive profiles in the current dive series. It will also change these calculations according to the personal adjustment you select.

The pattern and speed of decompression at the surface is adjusted according to micro-bubble influence.
