Acute Careniche
A 68-year-old woman is brought to a Perth emergency department unconscious after her neighbour found her with empty amitriptyline packets and a note. Her airway is at risk and her blood pressure is 78/40 mmHg. Her handbag holds a completed Western Australian advance health directive, signed and witnessed two years ago, refusing intubation, ventilation and cardiopulmonary resuscitation, together with an enduring power of guardianship appointing her brother, who is now on the telephone. Her daughter is at the bedside and asks that the directive be respected. Which one of the following is the legally correct course?
