A '''decompression algorithm''' is used to calculate the [[decompression stop]]s needed for a particular [[dive profile]] to reduce the risk of [[decompression sickness]] occurring after surfacing at the end of a dive. The algorithm can be used to generate [[decompression tables]] or be implemented in [[dive computer]] software. |

== Deterministic Models == |
|||
[[Determinism|Deterministic]] decompression models are a rule based approach to calculating decompression. These models work from the idea that "excessive" [[supersaturation]] in various [[Tissue (biology)|tissues]] is "unsafe" (resulting in [[decompression sickness]]). They usually contain multiple depth and tissue dependent rules. These rules are revised by [[Qualitative data|qualitative]] [[judgement]]. There is no [[Objectivity (science)|objective]] mathematical way of evaluating the rules or overall [[risk]]. |
|||
== Probabilistic Models == |
|||
[[Probability|Probabilistic]] decompression models are designed to calculate the [[risk]] (or probability) of [[decompression sickness]] (DCS) occurring on a given decompression profile. These models can vary the [[decompression stop]] depths and times to arrive at a final decompression schedule that assumes a specified probability of DCS occurring. The model does this while minimizing the total decompression time. This process can also work in reverse allowing one to calculate the probability of DCS for any decompression schedule. |
|||
== Bubble Models == |
|||
[[Bubble]] decompression models are a rule based approach to calculating decompression. These models work from the idea that microscopic bubble nuclei always exist in water and tissues that contain water and that by predicting/ controlling the bubble growth, one can avoid decompression sickness. |
