Acute onset of breathing problems caused by fluid accumulation in lung extravascular spaces induced by immersion, usually in cold water, often with intense physical exertion. Symptoms reported developed during physical activity and usually include dyspnoea/shortness of breath and a cough, often haemoptysis, occasionally chest tightness, chest ...
The cold water can also cause heart attack due to vasoconstriction; [4] the heart has to work harder to pump the same volume of blood throughout the body, and for people with heart disease, this additional workload can cause the heart to go into arrest. A person who survives the initial minute of trauma after falling into icy water can survive ...
In the presence of a right-to-left shunt of the heart, such as a patent foramen ovale, venous bubbles may enter the arterial system, resulting in an arterial gas embolism. [ 12 ] [ 13 ] A similar effect, known as ebullism , may occur during explosive decompression , when water vapour forms bubbles in body fluids due to a dramatic reduction in ...
Carrying out in-water recompression when there is a nearby recompression chamber or without suitable equipment and training is never a desirable option. [105] [106] The risk of the procedure is due to the diver suffering from DCS being seriously ill and may become paralysed, unconscious or stop breathing while under water.

Generalized hypoxia occurs when breathing mixtures of gases with a low oxygen content, e.g. while diving underwater especially when using closed-circuit rebreather systems that control the amount of oxygen in the supplied air, or when breathing gas mixtures blended to prevent oxygen toxicity at depths below about 60 m near or at the surface ...
The disorders are caused by breathing gas at the high pressures encountered at the depth of the water and divers will often breathe a gas mixture different from air to mitigate these effects. Nitrox , which contains more oxygen and less nitrogen , is commonly used as a breathing gas to reduce the risk of decompression sickness at recreational ...
Red flag warnings were spotted at beaches across the Jersey Shore on Saturday, leaving the potential for lifeguards to close ocean access in the aftermath of Tropical Storm Debby.
