Explanation:
Ian remains in a coma after a serious diving accident. He is still on medical life support because he is unable to breathe and his heart will not beat without assistance. The accident likely caused damage to Ian’s medulla. The medulla oblongata is a part of the hind brain that is located at the brain stem and it is responsible for some autonomic functions such as breathing, swallowing, sneezing, heart and blood functioning.
