目的:估计囊性纤维化患者一氧化碳的弥散量(TLCO)并评价其对运动时动脉去饱和效应的预测能力。方法:通过测定44例囊性纤维化患者(9-30岁)TLCO和脚踏车试验来评价肺功能。这些患者的病情变化范围很大:Shwachman评分平均为77.8(40-100),
OBJECTIVE: To assess the carbon monoxide dispersion (TLCO) in patients with cystic fibrosis and evaluate their ability to predict arterial desaturation during exercise. METHODS: Lung function was assessed by measuring TLCO and cycling tests in 44 patients with cystic fibrosis (9-30 years). The condition of these patients varied widely: the Shwachman score averaged 77.8 (40-100),
