Abstract: A method of improvement of inhalation therapy including presenting audiovisual stimuli to a patient, where content of the audiovisual stimuli promotes a physiological response, such as an involuntary breathing response, such as a yawn. Also, an apparatus for improvement of inhalation therapy including an audiovisual stimuli presentation system, where the audiovisual stimuli presentation system presents audiovisual information to a patient, and where content of the audiovisual stimuli presentation system promotes a physiological response, such as an involuntary breathing response, such as a yawn. The method and apparatus may be particularly suited for a patient that is unable or unwilling to communicate with a respiratory therapist, such as pediatric patients or patients with a neurological disorder.
