Background: Although the impulse oscillometry system (IOS) is a noninvasive, easily accessible, well-tolerated, and alternative test, routine use of IOS in cystic fibrosis (CF) patients is not widespread. In our unit, IOS is routinely used for the evaluation and follow-up of patients with CF. We aimed to show that IOS may be utilized as a complement for measuring pulmonary function in CF patients.

脉冲示波系统是评估和随访囊性纤维化患者的有用方法吗？

背景：尽管脉冲示波法系统 (IOS) 是一种无创、易于获取、耐受性良好的替代测试，但在囊性纤维化 (CF) 患者中常规使用 IOS 并不普遍。在我们单位，IOS 常规用于 CF 患者的评估和随访。我们旨在证明 IOS 可用作测量 CF 患者肺功能的补充。
