老年人群中慢性支气管炎患者多,冬季寒冷,病人常因剧烈咳嗽而出现意识短暂丧失和跌倒现象。由于是在咳嗽或咳痰时发病的,中医称之为“痰厥”。 众所周知,慢性支气管炎等呼吸系统疾病会影响肺部的气体交换,妨碍二氧化碳的排出和氧气的摄入,造成机体不同程度的缺氧。而脑部对缺氧非常敏感,持续剧烈咳嗽本身就会让人感到上气不接下气,而且咳嗽时腹腔和胸腔内压增高,会妨碍静脉血的回流,使心脏输出血量减少,加重脑部缺血缺氧。此外,咳嗽时脑脊液压力增大使颅内压增高,也会引起脑部的一时性缺血。痰厥往往是在慢性支气管炎、支气管哮喘、肺气肿、肺心病、脑动脉硬化、冠心病等慢性呼吸系统、心脑血管系统疾病的基础上,因剧烈咳嗽而引发 Older people with chronic bronchitis, cold in winter, the patient often due to severe cough and loss of consciousness caused by a brief fall. As it is in the cough or sputum when the disease, Chinese medicine called “sputum Jue.” It is well-known that respiratory diseases such as chronic bronchitis affect the gas exchange in the lungs and prevent the discharge of carbon dioxide and the intake of oxygen, resulting in different degrees of hypoxia in the body. The brain is very sensitive to hypoxia, sustained severe cough itself will make people feel upside down, and when the abdominal cavity and chest pressure increased cough, will impede the return of venous blood, so that the output of blood to reduce the heart, increased Brain ischemia and hypoxia. In addition, increased pressure on the cerebrospinal fluid during cough increases intracranial pressure and may also cause temporary brain ischemia. The sputum is often caused by severe cough on the basis of chronic respiratory diseases such as chronic bronchitis, bronchial asthma, emphysema, pulmonary heart disease, cerebral arteriosclerosis and coronary heart disease and cardiovascular and cerebrovascular diseases
