Livre/Ouvrage ou monographie
The editors of and authors of this book are a cadre of scientists and physicians with broad experience and knowledge of diving physiology and decompression theory. As is often the case, it requires a group effort to succeed in advancing practical knowledge. The colloquialism "the whole is greater than the sum of its parts" is often true and the PHYPODE Reasearch Group epitomizes this concept. By ...
Preconditioning to Reduce Decompression Stress in Scuba Divers
18 janvier 2017,
- HE Bruxelles Brabant
,
- Article scientifique
Article scientifique
BACKGROUND: Using ultrasound imaging, vascular gas emboli (VGE) are observed after asymptomatic scuba dives and are considered a key element in the potential development of decompression sickness (DCS). Diving is also accompanied with vascular dysfunction, as measured by flow-mediated dilation (FMD). Previous studies showed significant intersubject variability to VGE for the same diving exposure and ...
Objective vs. Subjective Evaluation of Cognitive Performance During 0.4-MPa Dives Breathing Air or Nitrox

,
- Article scientifique
Article scientifique
BACKGROUND: Divers try to limit risks associated with their sport, for instance by breathing enriched air nitrox (EANx) instead of air. This double blinded, randomized trial was designed to see if the use of EANx could effectively improve cognitive performance while diving. METHODS: Eight volunteers performed two no-decompression dry dives breathing air or EANx for 20 min at 0.4 MPa. Cognitive ...
Patent Foramen Ovale (PFO), Personality Traits, and Iterative Decompression Sickness. Retrospective Analysis of 209 Cases

- Article scientifique
Article scientifique
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). 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 ...

"This book makes it easy to understand the latest discoveries in diving research. You will enjoy reading about our current understanding of what happens to our bodies when we dive." JP Imbert: Decompression designer and technical diving pioneer
"As a doctor with a fair history and understanding of diving medicine and diving physiology I found the book interesting. It's the sort of book I would ...
The effect of pre-dive ingestion of dark chocolate on endothelial function after a scuba dive
15 mars 2015,
- HE Bruxelles Brabant
,
- Article scientifique
Article scientifique
Objective: The aim of the study was to observe the effects of dark chocolate on endothelial function after scuba diving.
Methods: Forty-two male scuba divers were divided into two groups: a control (n=21) and a chocolate group (n=21). They performed a 33-metres deep scuba-air dive for 20 minutes in a diving pool (Nemo 33, Brussels). Water temperature was 33⁰C. The chocolate group ingested 30 g ...
Nitric oxide-related endothelial changes in breath-hold and scuba divers
01 mars 2013,
- HE Bruxelles Brabant
,
- Article scientifique
Article scientifique
Objective: Scuba and breath-hold divers are compared to investigate whether endothelial response changes are similar despite different exposure(s) to hyperoxia.
Design: 14 divers (nine scuba and five breath-holding) performed either one scuba dive (25m/25 minutes) or successive breath-hold dives at a depth of 20 meters, adding up to 25 minutes of immersion time in a diving pool. Flow-mediated ...
Dark chocolate reduces endothelial dysfunction after successive breath-hold dives in cool water
16 septembre 2013,
- HE Bruxelles Brabant
,
- Article scientifique
Article scientifique
Objective: The aim of this study is to observe the effects of dark chocolate on endothelial function after a series of successive apnea dives in non-thermoneutral water.
Methods: Twenty breath-hold divers were divided into two groups: a control group (8 males and 2 females) and a chocolate group (9 males and 1 female). The control group was asked to perform a series of dives to 20 m adding up to ...
Pre-dive Whole-Body Vibration Better Reduces Decompression-Induced Vascular Gas Emboli than Oxygenation or a Combination of Both
30 novembre 2016,
- HE Bruxelles Brabant
,
- Article scientifique
Article scientifique
Purpose: Since non-provocative dive profiles are no guarantor of protection against decompression sickness, novel means including pre-dive "preconditioning" interventions, are proposed for its prevention. This study investigated and compared the effect of pre-dive oxygenation, pre-dive whole body vibration or a combination of both on post-dive bubble formation. Methods: Six healthy volunteers performed ...
Critical Flicker Fusion Frequency: A Marker of Cerebral Arousal During Modified Gravitational Conditions Related to Parabolic Flights

- HE Bruxelles Brabant
,
- Article scientifique
Article scientifique
In situ evaluation of human brain performance and arousal remains challenging during operational circumstances, hence the need for a rapid, reliable and reproducible tool. Here we hypothesized that the Critical flicker fusion frequency (CFFF) reflecting/requiring visual integration, visuo-motor skills and decision-taking process might be a powerful, fast and simple tool in modified gravity environments. ...
