Rescue still faces huge challenge, strengthens sea warfare persons falling in water self and mutual medical aid and maritime search and rescue ability to raising
Be rescued success rate, reduce mortality rate significant.
Research shows, temperature decline is one of chief threat of generally facing in briny environment of persons falling in water.
Owing to seawater surface mean temperature is relatively low, the whole world there are about the sea surface temperature in 66% marine site and is less than 25 DEG C, 46% marine site
Sea surface temperature less than 20 DEG C, when persons falling in water is directly exposed to such low temperature seawater environment, due to the heat transfer of water
Ability is much larger than air, and internal heat is quickly consumed by low temperature seawater, and body can only be by shrinking peripheral vascular
Reduce blood flow and muscle tremors produces more heat and maintains body temperature.But when with Cold Water Exposure overlong time,
Body then can not preserve or produce enough heats, and heat scatters and disappears and produces, under central body temperature starts more than heat
Fall, finally tends to ambient temperature.When central body temperature is down to 35 DEG C, persons falling in water there will be tired,
The symptoms such as ataxia, numbness, disorientation and abalienation;When being down to 32 DEG C, persons falling in water will
Unconsciousness, vein are withered, muscle rigidity, platycoria, arrhythmia, heart beating weaken, finally dead.
Research shows, the hypothermic mortality rate of middle severe is up to 30%~80%.
