A. Except as otherwise provided in the Oklahoma Do-Not-Resuscitate Act, a person's right to receive and a health care provider's responsibility to administer cardiopulmonary resuscitation shall not be impaired. Nothing in the Oklahoma Do-Not-Resuscitate Act shall impair or supersede a person's right to choose to have cardiopulmonary resuscitation withheld or provided or a health care provider's responsibility to withhold or provide cardiopulmonary resuscitation as provided by law. In this respect, the provisions of the Oklahoma Do-Not-Resuscitate Act are cumulative.

B. In the event of cardiac or respiratory arrest, a patient's attending physician or other health care provider must comply with such patient's request for cardiopulmonary resuscitation whether requested by such patient or such patient's representative, or required by such patient's advance directive.

C. Nothing in the Oklahoma Do-Not-Resuscitate Act shall be construed to preclude a court of competent jurisdiction from approving the issuance of a do-not-resuscitate order under circumstances other than those under which such an order may be issued pursuant to the provisions of the Oklahoma Do-Not-Resuscitate Act.

D. The provisions of the Oklahoma Do-Not-Resuscitate Act shall not affect the validity of do-not-resuscitate consents or orders that were executed prior to November 1, 1997.
