    • Physiology of repeated mixed gas 100-m wreck dives using a closed-circuit rebreather: a field bubble studyPeer reviewedOpen access 

      28 novembre 2021, BALESTRA, Costantinoorcid-id; Guerrero, François; THEUNISSEN, Sigrid; GERMONPRÉ, Peter; Lafère, Pierre, HE Bruxelles Brabant
      Article scientifique
      Purpose: Data regarding decompression stress after deep closed-circuit rebreather (CCR) dives are scarce. This study aimed to monitor technical divers during a wreck diving expedition and provide an insight in venous gas emboli (VGE) dynamics. Methods: Diving practices of ten technical divers were observed. They performed a series of three consecutive daily dives around 100 m. VGE counts were ...

    • Pre-dive Whole-Body Vibration Better Reduces Decompression-Induced Vascular Gas Emboli than Oxygenation or a Combination of BothPeer reviewedOpen access 

      30 novembre 2016, BALESTRA, Costantinoorcid-id; THEUNISSEN, Sigrid; Papadopoulou, Virginie; Le Mener, Cédric; GERMONPRÉ, Peter; Guerrero, François; Lafère, Pierre, HE Bruxelles Brabant
      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 ...

    • Preconditioning to Reduce Decompression Stress in Scuba DiversPeer reviewedClosed access 

      18 janvier 2017, GERMONPRÉ, Peter; BALESTRA, Costantinoorcid-id, HE Bruxelles Brabant
      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 ...

    • Scuba Physiological: Think You Know All About Scuba Medicine? Think again!Peer reviewedOpen access 

      01 décembre 2017, Pridmore, Simon; Balestra, Costantino; GERMONPRÉ, Peter, HE Bruxelles Brabant
      Livre/Ouvrage ou monographie
      "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 ...

    • Static Metabolic Bubbles as Precursors of Vascular Gas Emboli During Divers' Decompression: A Hypothesis Explaining Bubbling VariabilityPeer reviewedOpen access 

      30 juillet 2019, Imbert, Jean Pierre; Egi, Salih Murat; GERMONPRÉ, Peter; BALESTRA, Costantinoorcid-id, HE Bruxelles Brabant
      Article scientifique
      Introduction: The risk for decompression sickness (DCS) after hyperbaric exposures (such as SCUBA diving) has been linked to the presence and quantity of vascular gas emboli (VGE) after surfacing from the dive. These VGE can be semi-quantified by ultrasound Doppler and quantified via precordial echocardiography. However, for an identical dive, VGE monitoring of divers shows variations related to ...

    • Ultrasound lung "comets" increase after breath-hold divingPeer reviewedClosed access 

      23 octobre 2010, LAMBRECHTS, Kate; GERMONPRÉ, Peter; Charbel, Brian; Cialoni, Danilo; Musimu, Patrick; Sponsiello, Nicola; Marroni, Alessandro; Pastouret, Fredéric; BALESTRA, Costantinoorcid-id, HE Bruxelles Brabant
      Article scientifique
      The purpose of the study was to analyze the ultrasound lung comets (ULCs) variation, which are a sign of extra-vascular lung water. Forty-two healthy individuals performed breath-hold diving in different conditions: dynamic surface apnea; deep variable-weight apnea and shallow, face immersed without effort (static maximal and non-maximal). The number of ULCs was evaluated by means of an ultrasound ...

    • Varying Oxygen Partial Pressure Elicits Blood-Borne Microparticles Expressing Different Cell-Specific Proteins-Toward a Targeted Use of Oxygen?Peer reviewedOpen access 

      17 juillet 2022, BALESTRA, Costantinoorcid-id; Arya, Awadhesh; Leveque, Clément; Virgili, Fabio; GERMONPRÉ, Peter; LAMBRECHTS, Kate; Lafere, Pierre; Thom, Stephen, HE Bruxelles Brabant
      Article scientifique
      Oxygen is a powerful trigger for cellular reactions, but there are few comparative investigations assessing the effects over a large range of partial pressures. We investigated a metabolic response to single exposures to either normobaric (10%, 15%, 30%, 100%) or hyperbaric (1.4 ATA, 2.5 ATA) oxygen. Forty-eight healthy subjects (32 males/16 females; age: 43.7 +/- 13.4 years, height: 172.7 +/- 10.07 ...
