You are working in the emergency medicine department during a night shift. James, an 85 year old man with multiple co-morbidities goes into cardiopulmonary arrest on arrival to hospital, and cardiopulmonary resuscitation is started immediately. His daughter thinks that a ‘Do Not Attempt Cardiopulmonary Resuscitation’ (DNACPR) was completed in a previous hospital admission, but would need to check paperwork at James’ home. What is the most appropriate action?
