Background to methodology of new decompression models.
Current decompression algorithms are able to produce decompression schedules for a range of diving profiles. Different algorithms are used by different organisations, producing a range of different decompression solutions for a given dive profile. Some models are best suited for a particular range of depth/time profiles.
Algorithms do not allow specific body physiology profiles to be considered.
The bubble and gas diffusion models only take care of a small number of the variables necessary to predict a complete range of solutions required for all decompression solutions. For example, it is required that divers rest after decompression. However, what if the diver has to perform exercise after the dive. How should the decompression be adjusted to allow for this?
Approach to finding a universal algorithm
The approach being employed is to look at modeling the human body completely from a gas dynamics viewpoint. This includes models for bubbles, gas diffusion, tissue differences, gas transport and more..
This is an enormous task. So, is being approached one step at a time. The goal is that any person, with any physiology, with any dive profile with any diet will be able to get a decompression profile more suited to them and their physiological strengths and weaknesses.
First steps
VR Technology recently took part in a Maths Study Group at Southampton university. The purpose of this was two fold:
1. Analyse the assumptions and limitations of current models to then produce some improved mathematics to achieve a better bubble model that took into account more physiological factors of bubble growth.
2. To determine realistic productive areas of future modeling that could achieve a continuing improvement to the simple bubble model.
