Health care may be provided without consent to a patient who is unable to consent if no person authorized by Section 44-66-30 to make health care decisions for the patient is reasonably available and willing to make the decisions, and, in the reasonable medical judgment of the attending physician or other health care professional responsible for the care of the patient, the health care is necessary for the relief of suffering or restoration of bodily function or to preserve the life, health, or bodily integrity of the patient.
