Patients with chronic obstructive pulmonary disease (COPD) usually experience expiratory flow limitation EFL during spontaneous breathing at rest. There is an increased interest in the impulse oscillometry IOS as a non-invasive method for detecting EFL during spontaneous breathing. Objectives: To study sensitivity of the impulse oscillometry compared to spirometry in detection of airway obstruction in chronic Obstructive pulmonary Disease (COPD) patients. Also, to detect which frequency is more sensitive R5 or R20 for assessing airway resistance in COPD patients. Methods: Eighty COPD patients were in the study. Twenty healthy non-smoker subjects was included as a control group. Spirometry and IOS measurement were performed using master- Lab IOS unil with built in program for measuring spirometry (Masterscreen IOS 2011, erich jaeger GmbH, Germany). Results: There was a high significant difference in the sensitivity between impulse oscillometry and spirometry parameters in diagnosis of airway obstruction in COPD patients. Also, the R5 was the most significant IOS parameter for assessing airway resistance in COPD patient compared to R20 and X5. Conclusions: IOS is an effective, easy to perform, and a non-invasive method for the assessment of airway obstruction in obstructive pulmonary disorders
