In 2001, the American Society of Echocardiography (ASE) published a position paper that provided guidelines for the performance of contrast echocardiography by a sonographer. The paper focused on the sonographer’s role in four specific areas: understanding of microbubble physics and ultrasound instrumentation, recognition of indications for the use of contrast media, establishment of intravenous (IV) access privileges if necessary, and development of written policies for contrast agent infusion or injection. It is the purpose of this paper to update sonographers on developments in these four areas and to provide useful tips that assist in optimizing the use of contrast media in an echocardiography laboratory. This will include the optimal use of both saline and left-sided contrast media, as well as safety information and recommended policies for left sided contrast agent use
