Role of IOS in evaluation of patients with interstitial lung diseases

This study included 48 patients with interstitial lung diseases of different causes. Pulmonary function test by spirometry was done to measure FEV1, FVC, FEV1/FVC, MEF25-75 and pulmonary function test by impulse oscillometry (IOS). We measured R5, R20, X5, RF. Oxygen saturation and 6MWT. Results In our study 87% were females. The mean age in our study was 50.75±11.1. Mean X5 was low in ILD denoting restrictive pattern, and there was a negative correlation between X5andFEV1/FVC. There was a positive correlation between X5and6MWT. The mean R5 was 150.33±while mean R20 was 108.33±48.66 this is within normal then this is considered an index of mild small airways obstruction.
