EpiFaith CV provides automatic aspiration and detection of arterial pressure as an alternative to manometry in central venous catheterization. The aim of the study is to evaluate if it may reduce operation time compared with conventional syringe.

Central venous catheterization (CVC) is crucial in modern perioperative and intensive care. Keeping constant and stable negative pressure while advancing the needle had been issue for beginners. Recently, EpiFaith CV provides a new solution for CVC, which facilitates syringe control and precision during assessing vessels. It provides steady aspiration and detection of arterial pressure as an alternative to manometry without the need to disconnect nor more connections. The aim of the study is to evaluate if it may reduce operation time compared with conventional syringe.
