肺心病时,维持机体的电解质与酸硷平衡,对提高疗效和改善预后有重要的意义;而此二者的平衡和变动关系非常密切,又相互影响。本文拟从临床实用角度阐述肺心病的电解质紊乱与酸硷失衡的变化规律。一、肺心病的电解质紊乱与酸硷失衡的机体代偿机制: 机体为了维护内环境的稳定,使pH保持在7.5～7.45之间及电解质平衡,以保证组织细胞进行正常代谢,主要依赖体内缓冲系统、肺功能调节和肾功能调节三种代偿反应机制进行维持。肺心病时,由于肺毛细血管床严重破坏,通气换气障碍,通气—血流比率失调,
Pulmonary heart disease, to maintain the body’s electrolyte and acid-base balance, to improve the efficacy and improve prognosis of great significance; and the balance between the two and the relationship is very close and influence each other. This article intends to explain the changes of electrolyte imbalance and acid-base imbalance in pulmonary heart disease from a clinical practical point of view. First, the electrolyte imbalance of pulmonary heart disease and acid-base imbalance of the body compensatory mechanism: the body in order to maintain the stability of the internal environment, the pH maintained at between 7.5 to 7.45 and electrolyte balance to ensure normal metabolism of tissue cells, mainly dependent on the body buffer System, regulation of lung function and regulation of renal function three compensatory response mechanism to maintain. Pulmonary heart disease, due to severe damage to the pulmonary capillary bed, ventilation problems, ventilation - blood flow rate imbalance,
