BACKGROUND Immersion pulmonary edema is potentially a catastrophic condition; however, the pathophysiological mechanisms are ill-defined. This study assessed the individual and combined effects of exertion and negative pressure breathing on the cardiovascular system during the development of pulmonary edema in SCUBA divers. METHODS Sixteen male professional SCUBA divers performed four SCUBA d...

INTRODUCTION An individual case review of diving-related deaths reported as occurring in Australia in 2006 was conducted as part of the Divers Alert Network Asia-Pacific (DAN AP) dive fatality reporting project. METHOD The case studies were compiled using reports from witnesses, the police and coroners. In each case, the particular circumstances of the accident and details from the post-morte...

Two Sustainable Development Goals are focused directly on combating the impacts of climate change coral reef communities: Goal 13, Climate Action (Take urgent action to combat and its impacts) 14, Life Below Water (Conserve sustainably use oceans, seas marine resources for sustainable development). Citizen science (CS) features prominently in a range programs that have been developed address SD...

Scuba diving allows for underwater visitation of cultural and natural resources. Underwater routes can be used as a tool for guided and supervised underwater visits. Two scuba diving routes were implemented in the Algarve (South of Portugal), the “B24” and “Poço” diving sites. The perceptions of scuba divers regarding several aspects of the routes and the existing support infrastructures were s...

During scuba diving, the circulatory system is stressed by an elevated partial pressure of oxygen while the diver is submerged and by decompression-induced gas bubbles on ascent to the surface. This diving-induced stress may trigger decompression illness, but the majority of dives are asymptomatic. In this study we have mapped divers' blood transcriptomes with the aim of identifying genes, biol...

Recreational SCUBA diving is widespread and increasing on coral reefs worldwide. Standard open-circuit equipment inherently noisy and, by seeking out areas of high biodiversity, divers inadvertently expose reef communities to an intrusive source anthropogenic noise. Currently, little known about noise as acoustic stressor, there a general lack empirical evidence community-level impacts reefs. H...

There has been an increasing demand on the part of scuba diving instructors and other diving authorities for a re-evaluation of emergency ascent procedures. Many diving medical authorities challenge the inclusion of open water free ascent or emergency controlled swimming ascent training in basic and advanced sport diving courses. In essence, they feel that-the potential risk of lung barotrauma ...
