Therefore, it seems to be a direct relationship between “cerebral” forms of DCS and PFO ( Balestra et al., 1998, 2004 Germonpre et al., 1998 Ries et al., 1999 Cantais et al., 2003 Mitchell and Doolette, 2009 Wilmshurst et al., 2015). Indeed, PFO is a pathway through which vascular gas emboli (VGE) can arterialize, given sufficiently favorable circumstances (such as large amount of VGE, PFO grading, straining maneuvers, delayed desaturation, etc.). It has been well associated to certain forms of DCS. One of them, the Patency of Foramen Ovale (PFO), a condition that is present in about one third of the human population is a heritage of the fetal cardiac circulation ( Hagen et al., 1984). Although, the precise mechanisms are not known, many provocating factors have been advocated in bubble formation or consequences ( Carturan et al., 1999 Blatteau et al., 2008 Germonpre et al., 2009). These problems (DCS: Decompression Sickness) are caused by gas bubbles formation in the blood vessels and/or supersaturated body tissues ( Germonpre et al., 2015). Upon their ascent and in the hours after the dive, SCUBA divers expose themselves to possible nitrogen decompression problems. Further work is needed to ascertain whether selected personality characteristics or PFO should be taken into account in the clearance decision to resume diving. Multiple-times injured significantly scored higher than control group on thrill and adventure seeking (TAS), experience seeking, boredom susceptibility and total score.Ĭonclusion: There is an inability of injured diver to adopt conservative dive profile after a DCS. There is also an increase of PFO prevalence among multiple injured divers (1st DCS: 66.4% 2nd & 3rd DCS: 100%) with a significant increase in PFO grade. The average depth significantly increases with previous occurrences of DCS (1st DCS: 31.8 ± 7.9 mfw 2nd DCS: 35.5 ± 9.8 mfw 3rd DCS: 43.4 ± 6.1 mfw). Results: 41.2% of all injured came for iterative DCS.

Twenty-three injured divers were tested using the Zuckerman's Sensation Seeking Scale V and compared to a matched group not involved in risky activities. Demographics, dive parameters, and PFO grading were recorded. From the available 594 records we excluded all cases with tentative diagnosis, medullary DCS or unreliability of reported dive profile, leaving 209 divers records with cerebral DCS for analysis. Methods: By crossing information obtained from Belgian Hyperbaric Centers, DAN Emergency Hotline, the press, and Internet diving forums, it was possible to be accountable for the majority if not all DCS, which have occurred in Belgium from January 1993 to June 2013. Introduction: There is a need to evaluate the influence of risk factors such as patency of foramen ovale (PFO) or “daredevil” psychological profile on contra-indication policy after a decompression sickness (DCS). 7Centre for Hyperbaric Oxygen Therapy, Military Hospital Queen Astrid, Brussels, Belgium.6Environmental, Occupational, Ageing (Integrative) Physiology Laboratory, Haute Ecole Bruxelles-Brabant, Brussels, Belgium.5Anatomical Research Training and Education, Vrije Universiteit Brussel, Brussels, Belgium.4Motor Sciences, Université libre de Bruxelles, Brussels, Belgium.
