A small mechanical device that incorporates a high-densityball bearing
Expiratory airflowmoves the ball bearing producing both positive expiratory pressure (PEP) and high frequencyoscillations of airwithin the airways
done in sitting
Effects of the Flutter:
Production of positive expiratory pressure causes an increase in end expiratory lung volume therefore reducing airway resistance and small airway closure
Channels of collateral ventilation are recruited allowing air to flow behindsputum plugs, facilitating secretion movement
High frequencyoscillations create airway vibrations that mobilise excess secretions
Reducessputum viscoelasticity
Flutter Technique:
Usually used in sitting or supine
Breathein through nose and out through the Flutter
Start with 4 - 8 quite deep inspirations with inspiratory hold, expiringagainst Flutter (mucus loosening stage)
Then onemaximal inspiration with inspiratory hold, followed by a forced expiration through the Flutter (mucus elimination stage)
