睡眠呼吸暂停综合征(SAS)患者可以出现夜间肺动脉高压。为评价SAS患者白天并发肺动脉高压(PAH)的情况及其发生机理,作者进行以下研究。 方法 在多导睡眠图(PSG)监测确诊的69例SAS患者中,选择呼吸暂停指数(AI)大于20/h或呼吸暂停/低通气指数(AHI)大于30的患者,并排除合并了COPD、近2月内有支气管-肺部感染以及心衰或呼吸衰竭的SAS患者等病例。共计有44例SAS进入该研究。所有患者进行白天血气分析、肺通气功能测定、右心漂浮导管检查以及全夜的多
Patients with sleep apnea syndrome (SAS) may have nocturnal pulmonary hypertension. To assess the prevalence and pathogenesis of pulmonary hypertension (PAH) in patients with SAS during daytime, the authors conducted the following study. Methods Sixty-nine patients with SAS diagnosed by polysomnography (PSG) were enrolled in this study. Patients with apnea index (AI) greater than 20 / h or apnea / hypopnea index (AHI) greater than 30 were excluded and patients with COPD were excluded. Nearly two months there are cases of bronchial-pulmonary infection and heart failure or respiratory failure in SAS patients. A total of 44 SAS patients entered the study. All patients underwent daytime blood gas analysis, pulmonary ventilatory function tests, right heart floating catheter tests, and overnight
