Currently the concept of micronuclei control or modification is not addressed by dive computers or models. [It is a portion of the model that is used to develop some NASA decompression procedures.]
In the algorithm (= calculation method) originally developed by J.S. Haldane at the turn of the century, it was thought that all inert gas in the body was dissolved and remained so during a safe, DCS-free decompression. At the time Doppler ultrasound flow meters were introduced as research tools into diving by M.P. Spencer and S. Campbell (Bulletin of the Mason Clinic, 22, 26-32, 1968), it was believed that gas bubbles never formed during ascent on, e.g., the US Navy dive Tables. It was reasoned that, if you monitored a diver and detected bubbles during the ascent, DCS would develop shortly thereafter. Doppler was thought to aid safe decompression, because you could simple stop the ascent and hold until the bubbles vanished. The results were otherwise, and when animals and humans were monitored on Navy schedules, many subjects display evidence of bubble formation. Obviously bubbles = bends was not a correct relationship. Bubble-free decompressions turned out to require an inordinate and excessive amount of time and were not cost effective.
In time, it was realized that many decompressions could be accompanied by the presence of bubble formation but were in fact DCS free. Later studies indicated that these Doppler bubbles were from the circulatory system (probably originating in or near the capillaries) of muscle and fat tissue and not the ones responsible for joint-pain DCS, i.e., the bends. The idea began to take hold that all, real decompressions could be bubble-forming ones, to a more or less degree. Furthermore, these bubbles were not being considered by the dive tables with respect to the transport of dissolved gas.
In general, gas bubbles are not particularly numerous during decompression and do not appear to interfere with the Haldanian calculation algorithm, the basis of virtually all commonly-employed dive tables and computer programs. If bubble formation is not excessive, table calculations are valid and even repetitive decompressions are possible and safe. These concepts were checked in the laboratory during the development of the Recreational Dive Planner [Hamilton, Rodgers, Powell, and Vann. Development And Validation Of No-stop Decompression Procedures For Recreational Diving. Diving Science and Technology. February 28, 1994, (pp. 78 + appendix)]. If for some reason, gas phase formation is excessive, real problems can develop and DCS result. Nucleation is one local effect, but this cannot be measured nor can nuclei concentration be inserted into the table or computer calculation.
You can apparently give yourself the protective edge by avoiding straining (e.g., climbing ladders with full gear, both pre- and post dive) and promoting blood circulation (e.g., remain moderately active post dive).
As far as printed tables or dive computers go, the underlying algorithm is the same. Several decades ago, it was thought that you could have a phone line to the laboratory that printed the tables and have an on-the-spot table made for you. The calculation method would be the same for the printed version in the book as for the custom-made version. Both methods are the same. With todays small computers, we can dispense with the phone line to the computation lab - - but the algorithm is still the same. Dive computers, however, do not round up the time/depth combinations; they tell you exactly where you are in time-pressure space.
But, it is a road map not a license
