MRCP2-0860
A 30-year-old office worker has been rushed to the emergency department after being rescued from a fire in her apartment. She has signs of smoke inhalation, with soot present in her nostrils and on the roof of her mouth. Her carboxyhaemoglobin level is 3%, and she has been experiencing a decreased level of consciousness since arriving at the hospital. There is no evidence of head trauma, and 600 μg of naloxone have not resulted in any improvement in her conscious level. You suspect that she may be suffering from hydrogen cyanide poisoning. Her blood pressure is 90/50 mmHg, with a pulse of 100/min and regular.
What is the most appropriate course of action in this situation?
