Diving Injuries At A Glance

Many injuries are related to the high pressure which is located above water weight and additionally based on the depth or in a caisson on the on the surface lying above the air pressure. At a depth of 10 m the sea water exerts a pressure which is equal to the standard atmospheric pressure at sea level, which is 1.03 kg / cm2 and 760 mm Hg absolute or an atmosphere (atm abs) is; therefore, the total pressure at this depth 2 atm abs. Any further decrease by 10 m means an additional increase in pressure to 1 atm.

Over 1,000 injuries occur annually in the US in diving before, of which> 10% fatal. Similar injuries can occur in which compressed air is used to keep water away from the work site in workers in tunnels or in caissons (watertight containers that are used for construction sites). Many injuries are related to the high pressure which is located above water weight and additionally based on the depth or in a caisson on the on the surface lying above the air pressure. At a depth of 10 m the sea water exerts a pressure which is equal to the standard atmospheric pressure at sea level, which is 1.03 kg / cm2 and 760 mm Hg absolute or an atmosphere (atm abs) is; therefore, the total pressure at this depth 2 atm abs. Any further decrease by 10 m means an additional increase in pressure to 1 atm. The gas volume in the body compartments is inversely proportional to the external pressure; an increase or decrease of the gas volume due to changes in pressure exerts a direct physical strength, may affect the different types of body tissue in its function (barotrauma). The amount of dissolved gases in the blood stream increases with increasing ambient pressure. An increased gas content can directly cause injury (z. B. Nitrogennarkose, oxygen toxicity) or indirectly during the emergence from the depth when N2 bubbles are released due to the decompression of the supersaturated blood flow (DCS). An arterial gas embolism can set as a result of barotrauma or decompression. Some medical disorders may, if they occur at depth, cause disability or confusion, which can lead to drowning (see table: Special medical contraindications for diving). More related with diving diseases (eg. As drowning, hypothermia, trauma) are treated elsewhere in the MSD Manual. Doctors, patients care with injuries caused by diving or compressed air can (n. D.
