Hyperbaric oxygenation - assignment of 100% O2 for several hours in a sealed chamber with a pressure of more than 1 atm, which is gradually reduced to atmospheric pressure.
A caisson disease occurs when the pressure decreases rapidly (for example, when you ascend from a depth, leave the caisson or altitude chamber, or climb to a height).
Ionizing effects can be accompanied by physical damage (for example, from an explosion or a fall); Concomitant injury can be more life threatening than radiation exposure and requires priority treatment.
Symptoms of radiation damage depend on whether the ionizing radiation acts on the whole organism (acute radiation syndrome) or only on the part of the body.
Ionizing radiation damages tissues in different ways, depending on the type of radiation, its dose, degree and type of external influence. Symptoms can be local (for example, burns) or systemic (in particular, acute radiation sickness).
A lightning strike in a person can cause heart failure, loss of consciousness and temporary or permanent neurological disorders. Severe burns and internal injuries are rare.
Arterial gas embolism is a potentially catastrophic phenomenon that occurs when gas bubbles enter the arterial system or form in it and clog the lumen of the vessels, causing ischemia of the organs.
In the United States, there are more than 1,000 damages per year associated with scuba diving, of which> 10% end fatal. Similar damage can occur to workers in tunnels or caissons in which compressed air is used to remove water from working areas.
