    • Decompression induced bubble dynamics on ex vivo fat and muscle tissue surfaces with a new experimental set upPeer reviewedClosed access

      Vascular gas bubbles are routinely observed after scuba dives using ultrasound imaging, however the precise formation mechanism and site of these bubbles are still debated and growth from decompression in vivo has not been extensively studied, due in part to imaging difficulties. An experimental set-up was developed for optical recording of bubble growth and density on tissue surface area during ...

    • Decreased Incidence of Pulmonary Barotrauma After Discontinuation of Emergency Free Ascent TrainingPeer reviewedOpen access 

      22 août 2018, Lafère, Pierre; GERMONPRÉ, Peter; Guerrero, François; Marroni, Alessandro; BALESTRA, Costantino, HE Bruxelles Brabant
      Article scientifique
      INTRODUCTION: Because a significant association between training to perform emergency free ascent (EFA) and the occurrence of pulmonary barotrauma (PBT) was demonstrated in 2006, the Belgian Underwater Federation (BUF) decided to discontinue this procedure. An evaluation was needed 10 yr after the implementation of this change. METHODS: All medical records with a diagnosis of PBT that occurred in ...

    • Objective vs. Subjective Evaluation of Cognitive Performance During 0.4-MPa Dives Breathing Air or NitroxPeer reviewedClosed access 

      19 avril 2017, GERMONPRÉ, Peter; BALESTRA, Costantino; Hemelryck, Walter; Buzzacott, Peter; Lafère, Pierre, HE Bruxelles Brabant
      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 ...

    • Variability in circulating gas emboli after a same scuba diving exposurePeer reviewedClosed access 

      30 avril 2018, Papadopoulou, Virginie; Germonpré, Peter; Cosgrove, David; Eckersley, Robert; Dayton, Paul; Obeid, Georges; BOUTROS, Antoine; Tang, Meng-Txing; THEUNISSEN, Sigrid; BALESTRA, Costantino, HE Bruxelles Brabant
      Article scientifique
      PURPOSE: A reduction in ambient pressure or decompression from scuba diving can result in ultrasound-detectable venous gas emboli (VGE). These environmental exposures carry a risk of decompression sickness (DCS) which is mitigated by adherence to decompression schedules; however, bubbles are routinely observed for dives well within these limits and significant inter-personal variability in DCS risk ...
