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.
