Decreases in Diffusing Lung Capacity for Carbon Monoxide (DLCO) in Occupational Divers and Their Impact on Decompression Sickness Risks

France16 participantsStarted 2016-03-22

Plain-language summary

Diving disorders and particularly Decompression sickness (DCS) represent a major concern in recreational and occupational pressure-related activities. As a result of decompression from higher to lower ambient pressure bubbles which are formed in vascular flow and in tissues take part in embolism then resulting in DCS. Individual factors such as vascular or respiratory defects are now considered to increase the risk of this dysbarism disease.

Inclusion Criteria: * Be professional and voluntary diver * Man or woman aged 18 years or older * Diffusing Lung Capacity for Carbon Monoxide measured beforehand in the study * No medical contraindication for hyperbaric * No hyperbaric constraint in 3 days before the dive * No prior Decompression sickness * Not to follow medicinal treatment modifying the vascular endothelial and/or the coagulation and/or the respiratory function * Patient affiliated to social security * Informed and signed Exclusion Criteria: * Concomitant pathology identified by the Investigator, justifying a contraindication for hyperbaric * Pregnant and nursing mothers * Patient who refuse to sign consent form

What they're measuring

Venous bubbles will be detected by precordial Doppler

Timeframe: 30 minutes after the dive
