慢性肺心病(简称肺心病)是国内常见病和多发病之一,住院患者病死率为12～25%,(引自1983年全国第四次肺心病专业会议资料)呼吸衰竭为其主要死因。肺心病的呼吸衰竭是指外呼吸功能严重障碍,导致动脉血氧分压(PaO_2)低于60毫米汞柱,动脉血二氧化碳分压(PaCO_2)高于50毫米汞柱,因此低氧血症是呼吸衰竭的重要病理生理之一,而氧气治疗则是肺心病综合治疗中的重要的一环。现分三个方面介绍: 一、氧疗的生理基础对肺心病而言,氧疗的主要目的有二:一个是从
Chronic pulmonary heart disease (CFD) is one of the most common and frequently occurring diseases in the country. The mortality of inpatients is 12% to 25%. (The most important cause of death is respiratory failure (cited from the Fourth National CPD Conference in 1983). Respiratory failure of pulmonary heart disease refers to a severe impediment to exocrine function resulting in an arterial partial pressure of oxygen (PaO_2) of less than 60 mmHg and an arterial partial pressure of carbon dioxide (PaCO_2) of greater than 50 mmHg. Therefore, hypoxemia is Respiratory failure is one of the important pathophysiology, and oxygen therapy is an important part of comprehensive treatment of pulmonary heart disease. Now divided into three aspects: First, the physiological basis of oxygen therapy For pulmonary heart disease, the main purpose of oxygen therapy are two: one is from
