During vibration, the caregiver places their flat hand firmly against the chest wall, atop the appropriate lung segment to be drained. The caregiver then stiffens their arm and shoulder, applies light pressure and creates a shaking movement, similar to that of a mechanical vibrating device. The patient should be instructed to breathe in deeply during vibration therapy, and exhale slowly and completely. Taking a deep breath and then exhaling slowly and forcefully without straining will help stimulate a productive cough.
