Impulse Oscillometry to Differentiate Chronic Obstructive Pulmonary Diseases and Bronchial Asthma
Esraa Mohammed Mohammed Hamza;
Abstract
SUMMARY
C
hronic Obstructive Pulmonary Disease (COPD), a common preventable and treatable disease, is characterized by persistent airflow limitation that is usually progressive and associated with an enhanced chronic inflammatory response in the airways and the lung to noxious particles or gases (Gold, 2017).
Conversely, asthma shows reversible airflow limitations due to the constriction of airway smooth muscle, edema of the airway walls, mucous hypersecretion and increased airway inflammation (O’Donnell et al., 2001).
The distribution of airway narrowing and the physiological mechanisms of airflow limitation may differ among asthma and COPD patients. However, spirometry cannot always distinguish the pathological and physiological mechanisms of airflow limitation due to asthma or COPD (Diaz et al., 2000).
The impulse oscillation system (IOS) has been introduced into clinical practice recently. The IOS is a type of forced oscillation technique (FOT), which can evaluate respiratory resistance and reactance at various oscillatory frequencies to determine properties not assessable by spirometry (Beydon et al., 2007).
