225 ILCS 125/40
No person may use the title and designation of a "Licensed Perfusionist", "Certified Perfusionist", "Certified Clinical Perfusionist", "Perfusionist", or "CCP", either directly or indirectly, in connection with his or her profession or business, unless he or she has been issued a valid, existing license as a perfusionist under this Act.
No person may practice, offer to practice, attempt to practice, or hold himself or herself out to practice as a licensed perfusionist without being licensed under this Act. This does not mean that all of the aspects of practice listed in Sections 10 and 50 of this Act are practices or skills only a perfusionist can perform. Other licensed or certified persons may, if qualified, be allowed to perform some or all of these practices.
