Background Acute heart failure is a common presentation to Emergency Departments (ED) the world over. Amongst the most common presenting signs and symptoms is dyspnoea due to acute pulmonary oedema, a life-threatening emergency that if left untreated or poorly managed. There is increasing evidence demonstrating improved outcomes following the use of vasodilators or non-invasive ventilation for these patients in the emergency setting. Consequently, the potential exists that initiating these therapies in the prehospital setting will similarly improve outcomes.
