Q
  • External jugular venous pressure
A
  • The External Jugular V. may serve as an “internal barometer” since when venous pressure rises the External Jugular V. is much more prominent along it’s course on the lateral Neck.
  • This can be used a s a diagnostic tool for conditions such as heart failure, Superior Vena Cava obstruction, enlarged Supraclavicular Lymph Nodes or increased intrathoracic pressure.
