The Correlation of Hyperinflation Chest Radiographic Image with Spirometry in Chronic Obstructive Pulmonary Disease Patients


Chronic Obstructive Pulmonary Disease (COPD) is defined by irreversible airflow obstruction due to chronic inflammation airway, destruction of the lung parenchyma and narrowing of the small airways. In this way, a predominant feature of destructive parenchymal changes is referred to hyperinflation. The diagnosis of COPD is based on clinical and radiological findings, as well as functional respiratory and pathological anatomical changes. To show the correlation between hyperinflation chest radiography image and the severity of airflow obstruction, spirometry test was performed in COPD patients. This retrospective cross-sectional study was conducted in 40 patients in BBKPM, Surakarta between April and October 2016 who met our inclusion criteria.
The study variables were spirometry results and hyperinflation chest radiographic image. There were 36 males, and four females with age ranged from 19 to 60 years old. There was a significant correlation between hyperinflation chest radiographic image (DMHT/diaphragm height) and the severity of airway obstruction measured with spirometry. However, hyperinflation on chest radiography (LL/lung length) did not correlate with airway obstruction severity. DMHT/diaphragm height image was significantly correlated with the severity of airway obstruction in COPD patients. Thus, this image can be used as a predictor for the severity of obstruction.
