Boating and SCUBA Accidents, Low-Head Dams, and Beach Renourishment
Published in John R. Fletemeyer, Ivonne Schmid, Principles and Practices of Aquatic Law, 2018
Decompression sickness (sometimes called “the bends”) results from inadequate decompression and nitrogen bubbles coming out of suspension in the bloodstream. The DAN estimates that approximately 1,000 U.S. divers suffer from decompression sickness every year. Outcomes can range from minor (temporary headache and confusion) to major (paralysis and even death).
Diving and ROV
Published in Sukumar Laik, Offshore Petroleum Drilling and Production, 2018
The term ‘decompression’ in diving derives from the reduction in ambient pressure experienced by the diver during the ascent at the end of a dive or hyperbaric exposure and refers to both the reduction in pressure and the process of allowing dissolved inert gases to be eliminated from the tissues during compression.
What to do about it?

Dynerman and Hayes (1991) interviewed several hundred people and, based on these interviews, came up with practical suggestions on how to balance work and private life. For instance, setting up clear boundaries between job and home, physically as well as psychologically, limit job spillover, pursue leisure activities that are fim and rewarding, and spend more time in the company of others. Cherniss (1995) followed 26 young professionals who suffered from early career burnout over 12 years and found that those who recovered were more successful at balancing work, family and leisure: The most successful professionals considered family commitments and leisure pursuits to be at least as important as their careers. They didn't simply work to live, as the burned out professionals did but neither they just live to work. (p. 162).Maslach (1982b, pp. 101-103) pays special attention to making the transition from work to home by introducing the notion of 'decompression'. Decompression, the gradual transition out of a high pressure underwater environment, is a technique used by scuba divers in order to avoid physical damage and unpleasant sensations caused by the release of nitrogen bubbles into the bloodstream. In a similar vein, Maslach argues, people working in an environment of high emotional pressure need to 'decompress' before moving into the normal pressure of their private life. Decompression refers to any activity that occurs between working and non-working times and that allows one to unwind, relax, and leave the job behind before getting fully involved with one's private life. For instance, reading a book, gardening, window shopping, daydreaming, going for a walk, or taking a nap may all be used for this purpose.

Diving may be related to a series of health issues, with their severity ranging from mild or moderate (barotrauma of the ear, sea sickness) to potentially life-threatening [arterial gas embolism, decompression illness (DCI), and pulmonary barotraumas] (Sheeba & Sultan, 2014; Wohl, 2011). The underwater environment is characterised by an increased ambient pressure and low temperatures which pose a challenge to adaptive mechanisms of human physiology, particularly regarding the respiratory, cardiovascular and metabolic systems (Madsen, Hink, & Hyldegaard, 1994). For those reasons, safe diving requires optimal status of both mental and physical performance for divers to effectively adapt in a setting of continuously changing circumstances, requiring rapid decision making, especially in the case of emergencies (DeGorordo, Vallejo-Manzur, Chanin, & Varon, 2003).

Post-dive bubbles result from N2 supersaturation during decompression. Thus, also cells of the central nervous system will still be supersaturated. If so, N2 narcosis could persist to a certain extent. In fact, in one study decreased cognitive performance persisted for at least 30-min post-dive (Balestra, Lafere, & Germonpre, 2012).
