(a) The knowledge and skills for performing the functions of a certified respiratory therapist must be acquired by academic and clinical preparation in a respiratory care program supported, approved, or otherwise recognized by the board or by 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.
