一、淹溺的机理是什么? 根据经验及动物实验发现人或动物被水淹后,先是挣扎、憋气,导致肺内缺氧、二氧化碳分压增高。之后约90％的溺水病人开始喘息、然后大口吸水,当水灌入肺后,则反射性地引起喉头痉挛或再度憋气,于是缺氧越加严重。少数溺水病人(约10％)可始终无水吸入,个别的可有呕吐、呛咳或抽风、惊厥。极大 First, the drowning mechanism is what? Based on experience and animal experiments found that people or animals flooded, the first struggle, hold your breath, leading to hypoxia in the lungs, carbon dioxide partial pressure increased. After about 90% of drowning patients began to wheeze, and then suck the water, when the water into the lungs, the reflex caused by laryngeal spasm or re-suffocation, so the more serious hypoxia. A small number of drowning patients (about 10%) can always inhale anhydrous, individual may have vomiting, choking or ventilation, convulsions. great
