Hemoptysis is one of the common, critical respiratory complex etiology, hemoptysis asphyxia mainly blood not spit or blood clots blocking the airway may suf ocate rapidly fatal. Do count every minute and second, seize the opportune moment to the rescue, rapid hemostasis, prevent suf ocation. If not timely rescue can occur in several minutes, even life threatening. The mortality rate is high, must promptly suck blood or blood clots, relieve respiratory tract obstruction, to save the lives of patients. The patients were first endotracheal intubation, intraoperative pulmonary lobectomy, when the stability of the circulatory system, the outcome in patients with good, after 2 days of tracheal incision, incision closed tube after operation 20 days, 30 days after operation, patients can be discharged. Airway and treatment is the key.%大咯血是呼吸系统的常见危急重症之一，病因复杂，咯血窒息主要为血液不及时咯出或血块阻塞呼吸道时可因窒息迅速致死。抢救时要做到分秒必争、不失时机，迅速止血，防止窒息。如抢救不及时可在数分钟内发生窒息，甚至威胁生命。死亡率极高，必需及时吸出血液或血块，解除呼吸道阻塞，才能挽救患者生命。本例患者首先行气管插管，术中行肺叶切除术，当循环系统稳定后，患者转归良好，术后2d行气管切开，术后20d气管切开闭口，术后30d患者得以康复出院。通畅气道是救治关键。
