Tennessee Code Title 63. Professions of the Healing Arts § 63-27-107

(a) The knowledge and skills for performing the functions of a certified respiratory therapist shall be acquired by academic and clinical preparation in a respiratory care program approved by the Commission on Accreditation of Allied Health Education Programs (CAAHEP) or its successor organization or other accrediting organization recognized by the board or by certification from the National Board for Respiratory Care. Under the supervision of a physician, certified respiratory therapists may assume clinical responsibility for specified respiratory care modalities involving the application of well-defined therapeutic techniques.

(b) The certified respiratory therapist's role shall not require the exercising of independent, clinical judgment; however, the certified respiratory therapist may be expected to adjust or modify therapeutic techniques within well-defined procedures based on a limited range of patient responses. Therefore, the effective use of the certified respiratory therapist, especially in the critical care setting, shall require the supervision of a physician experienced in respiratory care. The certified respiratory therapist may accept telephone or verbal orders and responsibilities involving the supervision of respiratory care therapists and respiratory assistants.
