Comparison of Effects of Flutter Device versus Autogenic Drainage on Peak Expiratory Flow Rate, Oxygen Saturation, Respiratory Rate and Pulse Rate in COPD Patients

In an earlier comparative study reported between Flutter device and Autogenic Drainage, Skaria et al. [5], found that Flutter device is more effective than the forced expiratory technique i.e. Autogenic Drainage. They reported greater improvement in terms of oxygen saturation and peak expiratory flow rate in the patients of moderate chronic bronchitis, who had used Flutter device. Ernst et al. [6], also did a comparative study between Flutter and AD but on patients of cystic fibrosis. They reported that oscillations applied by Flutter are better capable of decreasing mucus viscoelasticity within the airways as compared to the Autogenic drainage.
