慢性肺心病时,由于通气,换气功能障碍,引起缺氧和CO_2潴留,导致酸碱失衡,如诊断处理不及时,往往造成病人严重的后果。本文就有关慢性呼吸性酸中毒及复合型酸碱失衡的临床问题作一综述。一、呼吸性酸中毒发生机制和代偿程度肺心病由于感染引起气道阻塞,肺泡通气不足,血中CO_2潴留,导致呼吸性酸中毒。“呼酸”是肺心病最基本的酸碱失衡类型,发生率47.8～
Chronic pulmonary heart disease, due to ventilation, ventilation dysfunction, causing hypoxia and CO 2 retention, resulting in acid-base imbalance, such as the diagnosis and treatment is not timely, often result in serious consequences for the patient. This article reviews the clinical issues related to chronic respiratory acidosis and complex acid-base imbalance. First, the mechanism of respiratory acidosis and compensatory degree Pulmonary heart disease due to infection caused by airway obstruction, lack of alveolar ventilation, blood CO 2 retention, resulting in respiratory acidosis. “Hu sour” is the most basic type of pulmonary heart disease acid-base imbalance, the incidence of 47.8 ~
