The Suunto RGBM/ Deep Stop Algorithm
The Suunto Reduced Gradient Bubble Model (RGBM) utilized in the
Vytec predicts both dissolved and free gas in blood and tissues of divers.
It is a signifi cant advance on the classic Haldane models, which do not
predict free gas. The advantage of Suunto RGBM is additional safety
through its ability to adapt to a variety of situations and dive profi les.
The Suunto Vytec allows the user to choose between a traditional Rec-
ommended Safety Stop and Deep Stops. Deep Stops are decompres-
sion stops that occur deeper than traditional stops, with the purpose of
minimizing microbubble formation.
