Mr Chan is 84 years old and residing with his elderly. He has three adult children, who are all married and living apart. He was diagnosed with terminal cancer and was recently hospitalized for fever and acute confusion. The investigation results showed that he suffered multi-organ failure due to septicemia (a severe infection). Mr Chan had not signed any Advance Directives in relation to medical treatment when he was mentally sound. Therefore, the doctor discussed with his family to see if any invasive procedures (including ventilator, blood transfusion, pacemaker, etc.) and cardiopulmonary resuscitation should be performed on Mr. Chan. His family members have different views on this. His wife and one of the children want to try the best to extend his life, while the other two children just hope that their father can pass away without further suffering.
