{{Short description|Mathematical model of tissue inert gas uptake and release with pressure change}}

The '''Bühlmann desaturation''' set of parametersmodel is a pure Haldanian model (using Haldane's or Schreiner formula andcoupled with a simple parameterised expression for alveolar inert gas M-Valuespressure) which models the way [[inert gases]] enter and leave the human body as the [[ambient pressure]] changes.<ref name="AAB1984" /> Versions are used to create [[decompression tables]] and in personal dive computers to compute no-decompression limits and decompression schedules for dives in real-time, allowing [[Underwater diving|divers]] to plan the depth and duration for dives and the required [[decompression stops]].

The model (Haldane, 1908)<ref name="haldane" /> assumes [[Decompression theory#Perfusion limited tissues and parallel tissue models|perfusion limited gas exchange and multiple parallel tissue compartments]] and uses an [[Exponential decay|exponential formula]] for in-gassing and out-gassing, both of which are assumed to occur in the dissolved phase.
