DDU Critical Care Syllabus, Introduction Who is the DDU Critical Care for. A DDU certified doctor is a specialist medical practitioner who has overall responsibility. for ensuring the most accurate and valid information possible is obtained from the. ultrasound examination The DDU holder is then responsible for using the acquired. information to meaningfully contribute to clinical patient management The DDU holder. would usually have diagnostic ultrasound as a major focus of their practice and accept. referrals from a range of other medical practitioners as well as self referrals. The DDU holder has detailed specialist level knowledge and skill in all aspects of the. diagnostic ultrasound process When applicable this knowledge and skill may also apply. to therapeutic interventions processes, Candidates for the DDU Critical Care would usually be specialists working in. emergency medicine intensive care operating rooms and or be involved in undertaking. emergency retrievals Candidates for the DDU Critical Care would be expected to have. a significant component of their practice involved in the use of ultrasound for the. diagnosis assessment and intervention of acute medical problems leading to timely. determination of further clinical management The DDU candidate is expected to achieve. the recommended advanced level of critical care sonography as outlined in the. International Expert Statement on Training Standards for Critical Care Ultrasonography. published in Intensive Care Medicine 2011 37 1077 1083. The DDU Critical Care candidate would also be expected to be involved in teaching and. mentoring of less experienced practitioners research and development of innovative. clinical ultrasound techniques, OVERALL OBJECTIVES.
