Mandatory levels
Definition
Les paliers dits “obligatoires” sont tout simplement des paliers rendus nécessaires, en fonction du temps et de la profondeur de plongée :
- either bydive tables(precalculated values in tables);
- either by adive computer.
Today, almost 100% of divers usedive computers.
In the event of violation of the mandatory thresholds
The risk, in the event of violation of the mandatory stops (duration and/or depth), is to cause adesaturation accident: anarchic degassing of nitrogen bubbles in the body which can affect, among other things, the nervous system (paralysis, vision and speech disorders, etc.).

Curve of no-stop dives (mandatory)
Appelée improprement “courbe de sécurité”, la courbe des plongées sans paliers est un ensemble de couples de limites temps/profondeur qui permettent de remonter à surface sans avoir à effectuer de paliers obligatoires. Ces valeurs ne sont pas connues avec certitude, elles dépendent du modèle de désaturation utilisé.
