In order to explain his observations, Haldane suggested in his dive decompression theory that we consider the body as a group of tissues, and created a mathematical model to describe how each of the tissues absorbs and releases gases. He also noticed that divers could surface from a depth of 10 meters (33 feet), without developing DCS. Goats saturated to 50 msw (165 feet) did not develop DCS if decompressed to half the ambient pressure. Thanks to his experiments on goats, Haldane found that the body could tolerate a certain amount of excess gas with no apparent ill effects.

Haldane was the first researcher to apply a scientific approach to predicting and preventing decompression in a systemized way. Haldane Decompression Theory was proposed in 1908 by a Scottish physiologist John Scott Haldane, who is now considered to be the father of modern dive decompression theory. Let’s look at a few major theoretical models that serve as a basis for most of them: There are lots of algorithm variations and proprietary computations used in modern dive computers.

Finally, thanks to highly advanced microscopic physics experimentation and the use of mixed gases in diving today, the scientists are learning more about how different gases act in our bodies under pressure and update their algorithms accordingly. Another obvious source of difference is in determining the maximum acceptable risk. Why does this happen? One of the primary reasons lies in differing methods of interpreting the data and adjusting large numbers of initial best estimates. All dive computer algorithms are intended to keep the risk of decompression sickness (DCS) to an acceptable level and work using theoretical models, based on research and data from actual dives.Īlthough the source data for most algorithms is the same, the resulting calculations often differ. What Is a Dive Computer Algorithm?Ī dive computer algorithm is, in essence, a set of mathematical formulas used to calculate safe dive limits, factoring in a variety of real-time measurements, such as depth, time at that depth, water temperature, gas mix, cylinder pressure, ascent rate, etc.

So, let’s look at the theoretical models behind modern dive computer algorithms, the differences between the different options and the ways you can influence the algorithm. That being said, very few divers know which algorithm their dive computer uses and what it means for their diving.

A ll divers are taught how to use dive tables during their scuba course, but with dive computers becoming ever more widespread and affordable, most entrust calculating their safe dive limits to computer algorithms.
