An improved method and apparatus for respiratory audio-visual biofeedback are disclosed. A guide patterned after a breathing cycle comfortable to the patient serves as a target. The target is displayed as a bar moving vertically upward during inhale and vertically downward during exhale, between fixed end ex-hale and end in-hale limits. The patient's current respiratory position is also displayed as a bar, oriented parallel to the target bar so that the difference between the current position and the target position is easy for the patient to see.
