A highly sensitive movement suspended above the area of the greatest respiratory scans the patient’s breathing rhythm. The RBF-8000 amplifies the minimal electrical impulses converting them into two signals optical (lamps) and acoustical. Both signals develop in strict synchronization with in and exhalation. During inhalation brightness of the lamps and the volume of the sound increase while the lamps glow dimmer and the sound volume is softer during inhalation. The Patient lies on the coach and he/she is instructed to concentrate on the slow. The soothing rhythm of his/her breathing.
