Remember, the SIS title "Practice Guidelines" is not used in the traditional sense of guideline development that includes an exhaustive review of the literature, grading of the papers, and defining conclusions based on the degree of evidence. Instead this is a consensus statement on "best practices" of how to perform procedures, i.e. a cookbook of how SIS instructors and board members do these procedures in their practice. They effectively represent the "standard of care" view of the leaders of the SIS that may not translate to an identical standard of care by any other organization.
Furman's book, represents a sequential approach to procedure performance that places patient safety at a level of paramount importance. It has superb images, artwork, and conceptual realization.
