Various medical specialty organizations and the Agency for Healthcare Research and Quality (AHRQ) have advocated using ultrasonography to guide central venous cannulation. It is surprising then, that very few instructional models have been described to teach this technique. Consequently, we developed a model to teach ultrasound-guided central venous access. This paper presents a recipe for an ultrasonographic model or “phantom” that is easily made, inexpensive and simulates vessel cannulation extremely well.
