About this trial
This retrospective study aims at an epidemiological description of the clinical presentation of medical problems in technical diving. It assess anthropometric data, diving experience and dive planification, clinical presentation, treatment received and pronostic to understand specificity of this community.
Eligibility criteria
This trial does not accept healthy volunteersQualifiers
Civilian technical diver
Diving accident history (decompression sickness, biochemical accident or immersion pulmonary edema) following a technical dive in a trimix and/or rebreather dive
Treated in a hyperbaric center on the coast of mainland France
Disqualifiers
Participation denied by the diver
Diving incident diagnosis not retained by the hyperbaric physician
Trial population
Technical divers are defined by specialized equipment (e.g. rebreather) and/or helium based mixed-gases used to conduct deeper and longer dives. All divers who consulted hyperbaric installations after one of these dives with a retained diagnosis of a diving accident are eligible to participate.

Trial outcomes
Primary outcomes
Demographic description of injured technical divers treated in French hyperbaric center
Comparison of technical diver populations according to length of hospitalization (\< 48 hours vs \> 48 hours) corresponding to treatment with simple hyperbaric oxygen therapy or requiring several consolidation sessions in view of the severity and/or intensity of symptoms.
Secondary outcomes
Predictive factor of severity
Evaluation regarding the number of OHB treatment (reflecting the gravity if more than 2) and diving profil (breathing apparatus, maximal depth, dive total time, composition of mixed gas), demographic profile of divers (age, sex, medical conditions) and symptoms presentation.
