化学战剂是指战争中使用毒物杀伤对方有生力量、牵制和扰乱对方军事行动的有毒物质,是构成化学武器的基本要素。化学战剂应具备毒性强、作用快、毒效持久、施放后易造成杀伤浓度或战斗密度等条件,按照其性质可分为神经性毒剂、糜烂性毒剂、全身中毒性毒剂和窒息性毒剂等。其中窒息性毒剂又称肺刺激剂,如光气、双光气以及氯气、氯化苦等,主要损伤呼吸系统,引起急性中毒性肺水肿,导致缺氧和窒息~([1])。所以,对窒息性毒剂中毒 Chemical warfare agents refer to the poisonous substances used in war to kill each other’s forces, contain and disrupt other military operations and constitute the basic elements of chemical weapons. Chemical warfare agents should have strong toxicity, fast action, long-lasting toxic effects, easy to kill after release concentration or fighting density and other conditions, according to their nature can be divided into neurotoxic agents, erosive agents, systemic poisoning agents and asphyxiating agents . Among them, asphyxiating agents, also known as pulmonary stimulants, such as phosgene, phosgene, phosgene, chlorin and chloropicrin mainly damage the respiratory system and cause acute toxic pulmonary edema, resulting in hypoxia and asphyxia (1). Therefore, the poisoning of asphyxiation
