The American Association for Respiratory Care (AARC) is a non profit organization and is the only professional organization supporting Respiratory Care in the United States. In addition to attempting to help lobby for beneficial legislation nationally and locally, the AARC is trying to promote the profession as a whole to increase interest and membership. The AARC began in 1943, as the Inhalation Technician Association and has evolved rapidly and repeatedly since. Source: Wikipedia (en)
