The National Board for Respiratory Care, Inc. (NBRC) is a voluntary health certifying board which was
created in 1960 to evaluate the professional competence of respiratory therapists. A group of Chicago physicians
and therapists recognized the need to formalize the training and registration of practitioners involved in the
care and support of patients with respiratory disorders.
Through the guidance of these individuals, the American Registry of Inhalation Therapists (ARIT) was
incorporated as a not-for-profit corporation in the state of Illinois. This organization has responded to
the growth of the profession through the years and has evolved as the current NBRC.
