Post decompression records in echocardiography are considered to detect micro bubbles and to survey unexplained decompression sickness which is commonly examined by standardized methods such as dive computers and tables. In this study, existent bubbles are detected on transthoracic echicardiografic frames recorded after recreational diving. Bubble detection is performed by Artificial Neural Networks which are trained using bubbles with different morphologies. We showed that bubbles would be detected on four cardiac chambers without image segmentation.Lies mehr
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 if not all DCS, which have occurred in Belgium from January 1993 to June 2013.Lies mehr
Introduction: Scuba diving represents stressful event for cardiovascular system. Breathing with compressed air, hyperbaric environment and microbubbles formation are the main factors are the most influencing factors for pulmonary circulation. Hypothesis: The aim of the study was to evaluate the change in morphology and function of the right heart after scuba dive with compressed air.Lies mehr
Vascular gas bubbles are considered the principal element in decompression sickness (DCS) development. Traditionally these bubbles were called VGE (venous gas emboli), however scientific knowledge indicates that similar bubbles may also be present in the arterial circulation, therefore we propose to use “VGE” for “Vascular Gas Emboli”, and we will do so throughout the text. Reduction of VGE production represents an interesting endpoint to decrease decompression stress and DCS risk. Here we will discuss state of the art pre-dive techniques and approaches, commonly known as preconditioning, used to reduce post-dive VGE load and decompression stress. Evidence based approaches clearly show that some types of preconditioning are more potent in VGE reduction, some indecompression stress reduction and there are some with a positive impact on both. Nevertheless, further research is required to investigate the mechanisms underlying these positive effects.Lies mehr
The tenth European Consensus Conference on Hyperbaric Medicine took place in April 2016, attended by a large delegation of experts from Europe and elsewhere. The focus of the meeting was the revision of the European Committee on Hyperbaric Medicine (ECHM) list of accepted indications for hyperbaric oxygen treatment (HBOT), based on a thorough review of the best available research and evidence-based medicine (EBM).Lies mehr
