Prevalence of OSA in Patients of ILD

Pattern Of Association Between Obstructive Seep Apnea and Interstitial Lung Disease

To evaluate the clinical predictors of OSA in patients with ILD

Interstitial lung diseases (ILDs) are a group of heterogeneous disorders characterized by varying degrees of fibrosis and inflammation of lung parenchyma.

Obstructive sleep apnea is a type of sleep disordered breathing characterized by repeated episodes of apnea and hypopnea during sleep due to narrowing or occlusion of the upper airway.

It was found that the prevalence of OSA is as high as 80% among patients with idiopathic pulmonary fibrosis (IPF). Despite this common association, there is limited research in this field. There is great need for further studies to highlight this association and understand the underlying pathophysiological mechanisms implicated in those patients, to ultimately guide the appropriate management.

Inclusion Criteria:

• Patients presented to Chest Department with interstitial lung disease will be included, screened for OSA.

Exclusion Criteria:

• Age: less than 18 years. Unstable patients or need for ICU admission
