上呼吸道阻塞可导致肺的小动脉血管收缩、肺动脉高压、肺心病及右心衰竭。本文14例最后诊断为上呼吸道阻塞伴心力衰竭的病儿,3例出现全身性高血压,其中2例高血压如此严重,以致起初竟认为高血压可能为现有症状之病因,但随后病史表明,高血压乃上呼吸道阻塞伴心力衰竭的结果。有人曾研究低氧血症与睡眠呼吸暂停的关系,注意到在每次睡眠呼吸暂停发作时,动脉血压升高,其机理可能为低氧血症或/和呼吸性酸中毒(即高碳酸血症)引起交感神经张力增加;最后,因颅内压增高从而导致高血压。众所周知,心力衰竭本身使得周围血管收缩系通过交感神经
Upper airway obstruction can lead to pulmonary arteriolar vasoconstriction, pulmonary hypertension, pulmonary heart disease and right heart failure. Of the 14 patients who were finally diagnosed as having upper airway obstruction with heart failure, 3 had systemic hypertension, 2 of whom were so hypertensive that initially hypertension was thought to be the cause of the present symptoms, but the subsequent medical history showed Hypertension is the result of upper airway obstruction with heart failure. It has been studied the relationship between hypoxemia and sleep apnea, noted that during each sleep apnea, arterial blood pressure, the mechanism may be hypoxemia or / and respiratory acidosis (ie hypercapnia Symptoms) cause sympathetic tone increase; finally, due to increased intracranial pressure and thus lead to high blood pressure. It is well-known that heart failure itself causes the peripheral vasoconstriction to pass through the sympathetic nerve
