Nocturnal hypoxaemia is associated with adverse outcomes in interstitial lung disease

Sleep-disordered breathing (SDB) has been reported as highly prevalent in idiopathic pulmonary fibrosis (IPF) and other interstitial lung disease (ILD) populations. Nocturnal oxygen desaturation (NOD), or the total sleep time spent with SpoO2 < 90% (TST < 90), can occur both with and without associated apnoeas, and is common in ILD. This study aimed to characterize abnormal SDB and extent of TST < 90 in ILD patients and evaluate relationships...
