溺水是人体淹没于水,气道、肺泡为水堵塞,引起缺氧、二氧化碳积聚,导致呼吸性和代谢性酸中毒,严重者心搏骤停而死亡。溺水可分干溺及湿溺两种,干溺约占总死亡的10～20%,由于意外时突然产生反射性声门关闭及气管痉挛所致,气道和肺泡并无许多水份。溺水复苏后,呼吸和心跳虽已恢复,但数小时至4～5天内,可并发速脉、心律失常、低血压、高热、昏迷等,这种情况称淹溺综合症,是复苏后致死的主要原因,较易
Drowning is the human body submerged in water, airway, alveolar water blockage, causing hypoxia, carbon dioxide accumulation, leading to respiratory and metabolic acidosis, severe cardiac arrest and death. Drowning can be divided into two kinds of drowning and drowning, drowning accounts for about 10 to 20% of the total death, due to accidental reflex glottis closed and tracheal spasm caused by the airways and alveoli did not have much moisture. After drowning resuscitation, breathing and heartbeat have been restored, but within a few hours to 4 to 5 days, may be complicated by arrhythmias, hypotension, fever, coma, etc., this situation called drowning syndrome is lethal after resuscitation The main reason is easier
