Glucose pre-dive drink may prevent decompression sickness
Decompression sickness is caused by nitrogen being released from the blood too quickly, forming bubbles which may expand and injure tissue or block blood vessels. Anything that reduces bubble formation should decrease the risk of decompression sickness. Many factors increase the chance of decompression sickness, including dehydration. Researchers from the French Navy have found that drinking [...] -
Butterflyfish ‘May Face Extinction’
The Chevroned Butterflyfish may be at risk of extinction, scientists have warned. The case of the Chevroned Butterflyfish is a stark example of how human pressure on the world’s coral reefs is confronting certain species with ‘blind alleys’ from which they may be unable to escape, says Dr Morgan Pratchett of the ARC Centre of Excellence [...] -
Laser spots decompression sickness
Decompression sickness, it not treated quickly, can cause lasting damage and may even be fatal. Instead of waiting for symptoms to appear, a University of Houston professor is developing a laser-based system that can diagnose decompression sickness in a matter of seconds. Kirill Larin, assistant professor of biomedical engineering and mechanical engineering, is using a $400,000 [...] -
Researchers pronounce diving with asthma "safe"
SCUBA diving has grown in popularity, with millions of divers enjoying the sport worldwide. However, people with asthma are generally advised not to dive. This advice is ignored by large numbers of asthma sufferers. In a new study, Israeli researchers reviewed the scientific literature to evaluate the risks asthmatics take when diving. They found that [...] -
New Scale Developed to Diagnose Decompression Sickness
Researchers at the Hyperbaric Medicine Department, San Diego, have developed a three-point scale to diagnose decompression sickness. There are currently no universally accepted diagnostic criteria for the diagnosis of decompression sickness. The new SANDHOG (SAN Diego Diving and Hyperbaric Organizations) criteria uses a point scale and entrance level for the diagnosis of decompression sickness. [...] -
Decompression sickness causes lasting poor health
Poor health in former North Sea divers is associated with decompression sickness, according to a new report. A team from Haukeland University Hospital in Norway investigated the impact of decompression sickness and diving exposure on the health of Norwegian divers who previously worked in the North Sea. They questioned 230 ex-divers on their diving education and history [...] -
Diving Several Times a Day Damages the Ear
Diving several times a day during a week’s diving causes damage to the structures of the ear, Brazilian research suggests. Due to the condition known as middle ear squeeze, scuba diving has become one of the main causes of barotrauma. Barotrauma typically occurs to air spaces within a body when that body moves to or [...] -
Breath-Hold Divers Get Decompression Sickness Too
Decompression sickness, or the bends, is caused by nitrogen bubbles forming in the body. As the pressure reduces during ascent, the volume of gas in the blood and tissues increases. If the ascent is too fast the bubbles may reach a dangerous size and prevent blood flow or damage tissues. Normally associated with SCUBA [...] -
Nitric Oxide Reduces Bubble Formation in Divers
Prevention of bubble formation is a central goal in standard decompression procedures. According to research published in the FASEB Journal, nitric oxide reduces bubble formation following decompression after dives of different duration and to different depths. In their experiments, the researchers from the University of Split and the Norwegian University of Science and Technology gave [...] -
Diving And Subaquatic Medicine
New edition of the advanced text on clinical diving medicine. Now in it’s fourth edition, Diving and Subaquatic Medicine remains the leading text on diving medicine. This completely revised edition covers the newly described diseases of diving medicine, the modern types of diving and diving equipment, free and indigenous diving, as well as updating [...]
