Clustering of recreational divers by their health conditions in a database of a citizen science project
05 mai 2019, HE Bruxelles BrabantArticle scientifiqueDivers Alert Network Europe has created a database with a large amount of dive-related data that has been collected since 1993 within the scope of the Diving Safety Laboratory citizen science project. The main objectives of this study are the grouping divers by their health information and revealing significant differences in diving parameters using data mining techniques. Due to the methodology of ... -
Decreased Incidence of Pulmonary Barotrauma After Discontinuation of Emergency Free Ascent Training
22 août 2018, HE Bruxelles BrabantArticle scientifiqueINTRODUCTION: 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 ... -
Dive Risk Factors, Gas Bubble Formation, and Decompression Illness in Recreational SCUBA Diving: Analysis of DAN Europe DSL Data Base
10 mai 2017, HE Bruxelles BrabantArticle scientifiqueIntroduction: The popularity of SCUBA diving is steadily increasing together with the number of dives and correlated diseases per year. The rules that govern correct decompression procedures are considered well known even if the majority of Decompression Sickness (DCS) cases are considered unexpected confirming a bias in the "mathematical ability" to predict DCS by the current algorithms. Furthermore, ... -

Endothelial function may be enhanced in the cutaneous microcirculation after a single air dive
30 septembre 2020, HE Bruxelles BrabantArticle scientifiqueIntroduction: The effects of scuba diving on the vessel wall have been studied mainly at the level of large conduit arteries. Data regarding the microcirculation are scarce and indicate that these two vascular beds are affected differently by diving. Methods: We assessed the changes in cutaneous microcirculation before an air scuba dive, then 30 min and 24 h after surfacing. Endothelium-dependent ... -
Flying after diving: should recommendations be reviewed? In-flight echocardiographic study in bubble-prone and bubble-resistant divers
13 mai 2015, HE Bruxelles BrabantArticle scientifiqueINTRODUCTION: Inert gas accumulated after multiple recreational dives can generate tissue supersaturation and bubble formation when ambient pressure decreases. We hypothesized that this could happen even if divers respected the currently recommended 24-hour pre-flight surface interval (PFSI). METHODS: We performed transthoracic echocardiography (TTE) on a group of 56 healthy scuba divers (39 male, ... -
Heart Rate Variability During a Standard Dive: A Role for Inspired Oxygen Pressure?
13 août 2021, HE Bruxelles BrabantArticle scientifiqueIntroduction: Heart rate variability (HRV) during underwater diving has been infrequently investigated because of environment limitations and technical challenges. This study aims to analyze HRV changes while diving at variable hyperoxia when using open circuit (OC) air diving apparatus or at constant hyperoxia using a closed-circuit rebreather (CCR). We used HRV analysis in time and frequency domain ... -

Nitric oxide-related endothelial changes in breath-hold and scuba divers
01 mars 2013, HE Bruxelles BrabantArticle scientifiqueObjective: 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 ... -
Ultrasound lung "comets" increase after breath-hold diving
23 octobre 2010, HE Bruxelles BrabantArticle scientifiqueThe 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 ...
