Brief summary

The goal of this observational study is to compare the overnight heart rate variability (HRV) and nocturnal oxygen saturation (SpO2) in patients with idiopathic pulmonary fibrosis (IPF). The main questions it aims to answer are: (1). if there are correlations between pulmonary function test and HRV and overnight SpO2; (2). if HRV and SpO2 can predict the occurrence of acute exacerbation in patients with IPF. Participants will be asked to examine pulmonary function test (including lung volumes and six-minute walk test) and wear pulse oxygenation recorder and LARGAN ECG Holter (LARGAN HEALTH TECHNOLOGY Sleep Apnea And Sleep Quality Examination System) during sleep.
