(2) Determination of death pursuant to this section must be made in accordance with currently accepted reasonable medical standards.(a) If the patient’s treating health care practitioner is a physician licensed under chapter 458 or chapter 459, the determination must be made by that physician and a second physician licensed under chapter 458 or chapter 459 who is a board-eligible or board-certified neurologist, neurosurgeon, internist, family medicine physician, pediatrician, surgeon, or anesthesiologist.
