Rob Fenwick talks us through the key points of Carbon Monoxide poisoning and some recent evidence on the topic which will probably make us consider the possibility a bit more frequently! This podcast was based around the post Rob wrote for Jonathan Downham's superb Critical Care Practitioner podcast. Go and have a look at the post for a lot more information on the topic.
