A middle-aged woman is brought to the Emergency Department (ED), after being found unconscious in the town centre by members of the police. She is poorly kept, and a police handover reports that she has no fixed abode. She is well known to various members of ED. On arrival in ED, she is still unconscious. Her airway is patent; she is saturating at 94% on room air, with a respiratory rate of 10 breaths/min. She is haemodynamically stable, with a temperature of 35.6 °C and small, constricted pupils. There appears to be an area of minor external bleeding and a scalp haematoma on the back of her head.
