Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The Trendelenburg position is used to distend the central veins, improving both success and safety of vascular cannulation. The purpose of this study is to measure the cross-sectional area of the internal jugular vein (IJV) in three different positions, using surface ultrasound.
