The Frenzel maneuver describes a technique for middle ear equalizing which is frequently used by apnea divers. It offers advantages compared to the most commonly used techniques such as the Valsalva or Toynbee maneuver. Until now, there is insufficient literature about the pressure dynamics and Eustachian tube (ET) function during the Frenzel maneu...

It is speculated that diving might be harmful to the nervous system. The aim of this study was to determine if established markers of neuronal injury were increased in the blood after diving. Thirty-two divers performed two identical dives, 48 h apart, in a water-filled hyperbaric chamber pressurized to an equivalent of 42 m of sea water for 10 min...

Nowhere is redundancy more indispensable than extended range cave diving. Training and practice in this discipline ensure divers are equipped with backup regulators, gauges, lights, and adequate breathing gas for a safe exit, emergencies, and decompression. Depending on penetration distances and depth, open circuit cave diving may require carrying ...

This study aimed to describe recently active adult scuba divers in the United States (US) and compare their characteristics with other active adults. The research question was: do active scuba divers have different health and wellbeing characteristics, compared with adults active in other pursuits? The Behavioural Risk Factor Surveillance System (B...

Decompression sickness (DCS) has traditionally been categorized as type I DCS, affecting joints and skin, and type II affecting the nervous system. In the present study, we wanted to examine whether divers with a history of neurological DCS demonstrated a pattern of symptoms and clinical neurological and neurophysiological signs different from dive...

• Several ‘on-land’ studies had proven a reduced ventilation of exercising subjects in hyperoxia. • As O2-enriched breathing gas (ANx) is increasingly used published on-land results were translated into under-water results. • We demonstrate a novel EANx characteristic as under-water ventilation is also reduced with EANx compared with using air. • T...

The World for a Coral tells the story of divers who scour the reefs of Southeast Sulawesi, Indonesia, for beautiful and increasingly rare live corals for the global aquarium industry. Working on small wooden boats and breathing from makeshift air compressors, divers gather corals from reefs near the provincial capital city, Kendari, destined for sa...

Introduction Inner ear barotrauma (IEBt) and inner ear decompression sickness (IEDCS) are the two dysbaric inner ear injuries associated with diving. Both conditions manifest as cochleovestibular symptoms, causing difficulties in differential diagnosis and possibly delaying (or leading to inappropriate) treatment. Methods This was a systematic revi...

BackgroundWe report compelling evidence suggesting a predation event of a pop-up satellite archival tagged anadromous Dolly Varden (Salvelinus malma) by a marine mammal during summer in the Beaufort Sea based on abrupt changes in temperature and vertical movements. This observation provides insight on predator avoidance behaviour by Dolly Varden an...
