“…While this is compatible with the original Haldanian model, it is more difficult to envisage the parallel spectrum of inherent susceptibilities implied by the allotment of different decompression ratios to different theoretical tissues by later workers (Hawkins, Shilling and Hansen, 1945;Schreiner and Kelley, 1970;Workman, 1969;Yarborough, 1937). However, each of these could be heterogeneously perfused with blood and so give rise to a spectrum of response times, each region then being equivalent to a different theoretical tissue.…”

“…Consequently, it has been found necessary to apply several equations separately, each of the type depicted by equation 1, and then to base judgements according to the one indicating the lowest margin of safety at that particular time. Later authors have postulated fewer tissues, but usually more, until as many as 12 -14 have recently been proposed for simultaneous consideration (Schreiner and Kelley, 1970;Workman, 1967. 693/k where 0.…”

“…Another hypothetical tissue with the necessary half-time and ratio can always be produced to accommodate any resuit not conforming, particularly, when the selection of such tissues is facilitated by computer (Schreiner and Kelley, 1970). The bulk diffusion expressions offer a much more critical assessment of their respective models since each has only one degree of freedom in the form of constants which can be fixed empirically.…”

An Underwater Pathfinding Algorithm for Optimised Planning of Survey Dives

In scientific and technical diving, the survey of unknown or partially unexplored areas is a common task that requires an accurate planning for ensuring the optimal use of resources and the divers’ safety. In particular, in any kind of diving activity, it is essential to foresee the “dive profile” that represents the diver’s exposure to pressure over time, ensuring that the dive plan complies with the specific safety rules that have to be applied in accordance with the diver’s qualification and the environmental conditions. This paper presents a novel approach to dive planning based on an original underwater pathfinding algorithm that computes the best 3D path to follow during the dive in order to be able to maximise the number of points of interest (POIs) visited, while taking into account the safety limitations. The proposed approach, for the first time, considers the morphology of the 3D space in which the dive takes place to compute the best path, taking into account the decompression limits and avoiding the obstacles through the analysis of a 3D map of the site. Moreover, three different cost functions are proposed and evaluated to identify the one that could suit the divers’ needs better.

This chapter deals with the interrelated physiological effects of the continuum of altered ambient pressure. These pressures may be both higher and lower than the sea level pressure to which we are accustomed and in which we have evolved. The chapter first discusses what pressure is, and where and why alternative pressures are encountered by humans. It reviews the occupational, medical, and recreational incentives for forays into both environments, high and low. It points out the role of time in evaluating pressure exposures and the importance of transitions to and from higher and lower pressures. Then, it covers first the effects of elevated pressures, then the effects of lack of pressure, emphasizing the importance of breathing gases in most alternative pressures. Last, it pays particular attention to the main pressure‐related disorder, decompression sickness, and its treatment. This is a book on industrial hygiene and toxicology, so the chapter deals primarily with healthy individuals fit for the workplace, but does mention the special concerns about pressure needed for people who have various diseases.
