In this conversation we will examine the recent recommendations and development of a national out-of-hospital transfusion protocol for critical care services. We will unpack the recent modified RAND Delphi study that sets out the guidance of clinical governance and recommendations for out of hospital transfusion services. We will dig into the recommendations on the initiation of transfusion, the types of blood components and products, the delivery and monitoring of out of hospital transfusion, the Indications for and use of transfusion adjuncts and finally the resuscitation targets to halt ongoing transfusion.    Adam Greene is a Unit Chief and Critical Care Paramedic working at British Columbia Emergency Health Service.
