In-water recompression (IWR) or underwater oxygen treatment is the emergency treatment of decompression sickness by returning the diver underwater to help the gas bubbles in the tissues, which are causing the symptoms, to resolve.
Once it was recognised that the symptoms were caused by gas bubbles, [30] and that re-compression could relieve the symptoms, [29] [32] Paul Bert showed in 1878 that decompression sickness is caused by nitrogen bubbles released from tissues and blood during or after decompression, and showed the advantages of breathing oxygen after developing ...
A safety stop can significantly reduce decompression stress as indicated by venous gas emboli, but if remaining in the water to do a safety stop increases risk due to another hazard, such as running out of gas underwater or a significant medical emergency then the overall safety of the diver may be best served by omitting the safety stop.
Experts weigh in on claims associated with citrus, from the lime sleep hack to kidney stone prevention.
The water vapour may bloat the body to twice its normal volume and slow circulation, but tissues are elastic and strong enough to prevent rupture. Technically, ebullism is considered to begin at an elevation of around 19 kilometres (12 mi) or pressures less than 6.3 kPa (47 mm Hg ).At pressures where ebullism can occur, even 100% oxygen is not ...

Divers with the appropriate equipment and training can treat decompression sickness on-site. Such treatment may prevent long-term disability, and can reduce costs and risk to rescue personnel. In-water recompression is a viable alternative when safe and rapid transfer to a suitable recompression chamber is not practicable. [5]
The virus is found in the feces or vomit of a person who is sick, and is spread through drinking water or eating food that has been contaminated. Toys and other contaminated surfaces can also act ...
