Ultrasound protocols used to detect vascular gas emboli in divers: a systematic review

Introduction: Venous gas emboli (VGE) detected via ultrasound can be used as a surrogate marker for decompression stress. While Doppler ultrasound is the historical gold standard, two-dimensional (2D) ultrasonography offers advantages for on-site monitoring, including a wider fie...

Evaluating the FitMáx questionnaire for fitness-to-dive assessments in a military population

This study evaluated the validity of the FitMáx questionnaire for estimating VO2peak in 157 Dutch Navy divers and recompression personnel, a population characterised by high physical fitness and occupational demands. While self-reported questionnaires offer a logistically feasibl...

Impact of neoprene wetsuits on lung volumes and work of breathing: implications for military diver safety and performance

Introduction: Neoprene wetsuits may impose mechanical constraints on the chest wall, potentially altering respiratory function. This study investigated the impact of neoprene wetsuits on lung volumes, airway mechanics, and work of breathing (WOB) in healthy male divers. Methods:...

Mental health and neurodevelopmental factors relevant to recreational fitness-to-dive assessment: a structured review and clinical considerations

Introduction: Mental health and neurodevelopmental factors, including psychiatric disorders and psychotropic medication use, are commonly identified during recreational diving medical screening. However, guidance for fitness-to-dive assessment in this context remains limited and...
