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 significant 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 profiles.

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.
