About

EDE eBook

Features
Read full description

Since 2001, The Emergency Department Echo Course and The EDE 2 Course have taught EDE (pronounced β€œEddie”) to over 20000 physicians worldwide, including over half of the Canadian emergency medicine workforce. The most distinctive aspect of The EDE Courses has been the focus on image generation. When clinicians first began investigating the possibility of using ultrasound themselves, a big secret was concealed from them: image interpretation is easy. The real challenge is image generation: putting the image on the screen. Before The EDE Courses, physicians learned image generation mostly by trial and error. EDE brought a rigorous methodology to the scanning of each area of the body, dramatically reducing the time needed to master this new skill. ""Essentials of Point-of-Care Ultrasound"" combines The EDE Course manuals which have been written and re-written for over a decade to give health-care providers the clearest and most concise approach to bedside ultrasound. This β€œhow-to” guide contains over 700 illustrations, photos, and ultrasound images which show you how to perform the scan and how to recognize positive and negatives images. As well, the book focuses on how you can incorporate your findings into your clinical decision-making. The book also contains an approach to ultrasound guidance for several commonly performed procedures. This eBook adds the following functionalities: over 40 videos, slideshows, quizzes, reference hyperlinks to Pub Med, links to EDE blog content, an interactive glossary, chapter summaries, study cards and reader-defined notes, plus the easy-to-use navigation.
