Forced oscilation technique and hyperinflation in COPD
Abstract
Forced oscillation technique (FOT) is a simple method used to measure the mechanical impedance of the respiratory system.It can be a valuable test in poorly cooperative patients (pts) and in severe COPD.Little information exists concerning its value on hyperinflation in COPD pts.The aim of this study was to analyze the correlation (corr) between data obtained by FOT with data by body plethys-mography (P) in pts with COPD.No bronchodilator response analysis was done.
