N exchanges in hyperbaric environments: toward a model based on physiological gas transport (O and CO).

Decompression sickness can occur in divers even when recommended decompression procedures are followed. Furthermore, the physiological state of individuals can significantly affect bubbling variability. These informations highlight the need for personalized input to improve decompression in SCUBA diving.

Effects of hyperbaric exposure on mechanical and electronic parameters of implantable cardioverter-defibrillators.

Aims: Hyperbaric oxygen therapy (HBOT) is the standard adjuvant treatment for life-threatening or disabling pathologies. Currently, mechanical and electronic variations of implantable cardioverter-defibrillators (ICD) in hyperbaric conditions have not been evaluated. As a result, many patients eligible for HBOT but ICD recipients cannot undergo this therapy, even in emergency situations.

Risk factors for immersion pulmonary edema in recreational scuba divers: a case-control study.

Background: Immersion can cause immersion pulmonary edema (IPE) in previously healthy subjects. We performed a case-control study to better identify IPE risk factors.

Methods: We prospectively included recreational scuba divers who had presented signs of IPE and control divers who were randomly chosen among diving members of the French Underwater Federation.

Evolution of the respiratory function of professional divers over 15 years.

Background: The study was aimed at assessing changes in respiratory function after 15 years of profes- sional diving, among scientific divers.

Materials And Methods: A retrospective study was performed on divers who underwent an initial visit and a visit 15 years later at the same medical centre, among divers who had a scientific activity (monitoring the coastline, fauna and flora). Pulmonary function tests were performed in the same laboratory with the same operating standards and using a Jaeger MasterBody plethysmograph.

Infectious diseases affecting occupational divers: review of 2017 literature.

Background: Occupational divers are prone to many health risks. For instance, they can get infections. We reviewed the infectious diseases in occupational divers.

Health effects of hyperbaric exposure on chamber attendants: a literature review.

Background: Inside attendants working in hyperbaric chambers are exposed to risks related to the hyperbaric environment, handling and care. The aim of this study is to review the literature focusing on the impact of this activity on health.

Materials And Methods: This is a literature review using the Medline database.

Can a transgender person be an occupational diver? Demonstration from a case report.

This is the first case report about a transgender professional diver. The purpose of this article is to show the professional adaptations to help him to continue occupational dive and to raise the question of the impact on diving risks of hormonal treatment in this case. He was a 39-year-old man when he began his transition.

Occupational accidents among attendants inside hyperbaric chambers in France.

Introduction: The purpose of the study was to assess the number of accidents among staff employed in the operation of hyperbaric chambers in France.

Materials And Methods: A retrospective study using a questionnaire was carried out on occupational accidents in France between 2005 and 2011.

Results: 12 (46%) centres participated in the study, representing 73 subjects.

Longitudinal change in professional divers' lung function: literature review.

Background: The aim of this study was to assess changes in lung function of professional divers.

Materials And Methods: This is a review of the literature. Only studies about professional divers were included.

Swimming-induced immersion pulmonary edema while snorkeling can be rapidly life-threatening: case reports.

It is well known that immersion pulmonary edema can be life-threatening for divers using a self-contained underwater breathing apparatus (scuba). Swimming-induced pulmonary edema in otherwise healthy individuals is not an object of dispute but its real severity is not well known and is probably underestimated. We report two cases of life-threatening acute respiratory distress while swimming and snorkeling, one of which is well documented for swimming-induced pulmonary edema.

Reversible myocardial dysfunction and clinical outcome in scuba divers with immersion pulmonary edema.

Immersion pulmonary edema in scuba divers is a rare disorder that tends to recur and can be potentially fatal, even in the absence of underlying cardiac disease. Anecdotal cases of reversible myocardial dysfunction have been described in this setting, but little is known of its pathogenesis. The purpose of the present study was to determine the clinical outcomes and the determinants associated with this condition.

Cardiovascular risk factors and cardiovascular risk assessment in professional divers.

Background: The professional diver's activity implies body cardiovascular stress. Little data on cardiovascular risk factors is available. Some studies report a high prevalence of tobacco consumption.

Hemoptysis and pneumomediastinum after breath-hold diving in shallow water: a case report.

We report the case of a healthy 21-year-old woman who performed iterative breath-hold dives in relatively cold water, not exceeding depths of 5 meters but with "empty lungs." At the end of a dive, after experiencing an intense involuntary diaphragmatic contraction underwater, she presented hemoptysis followed by chest pain and cough. Chest radiography and computed tomography were performed 24 hours later, confirming the diagnosis of pneumomediastinum.

Prognostic factors of spinal cord decompression sickness in recreational diving: retrospective and multicentric analysis of 279 cases.

Background: This study aims to determine the potential risk factors associated with the development of severe diving-related spinal cord decompression sickness (DCS).

Methods: Two hundred and seventy nine injured recreational divers (42 ± 12 years; 53 women) presenting symptoms of spinal cord DCS were retrospectively included from seven hyperbaric centers in France and Belgium. Diving information, symptom latency after surfacing, time interval between symptom onset and hyperbaric treatment were studied.

Intracerebral hemorrhage related to systemic gas embolism during hysteroscopy.

Iatrogenic gas embolism is a rare but serious problem that has been documented in almost all medical specialties including gynecology. We present a 49-year-old woman undergoing operative hysteroscopy and myomectomy, who sustained sudden hypotension and decrease in the end-tidal carbon dioxid levels during the procedure. Systemic gas embolism was confirmed by echocardiographic evidence of bubbles in both right and left cardiac cavities and a rise of troponin.

[Pulmonary oedema in scuba-diving: frequency and seriousness about a series of 19 cases].

Objectives: Pulmonary oedema in self-contained underwater breathing apparatus diving is an accident whose risk factors, conditions of occurrence and incidence are not well-known. The aim of this study was to evaluate the frequency, the risk factors and the evolution of this accident.

Study Design: Retrospective case study and prospective frequency study.
