2-3 December, Sint-Niklaas, Belgium

Dive Expo is a special international event, held in Belgium, the heart of Europe, and addressed to all those divers interested in tech diving, and the latest trends in diving education and gear. 

DAN Europe participates at the conference with an interesting scientific talk by Prof. Costantino Balestra, and focused on Deep CCR (Closed-Circuit Rebreathers). 



by Prof. Costantino Balestra, VP DAN Europe Research

About the presentation

Deep diving using mixed gas with Closed-Circuit Rebreathers (CCRs) is increasingly common. However, data regarding the effects of these dives are still scarce. We investigated 3 major aspects of deep CCR Diving: Bubble Production, Pulmonary Function, Vascular Function. Research showed that, regardless of the gas mix used or the deco profile adopted, bubbles could be present, although no DCS occurred. Pulmonary function changes too during deep CCR Diving. Vascular function changes as well, but in the same magnitude than recreational dives.
