Cardiology Jugular Venous Pulse

Jugular Venous Pulse in Lung Disease

The jugular venous pulse can provide a clue to the presence of lung disease. Decreased intrathoracic pressure during inspiration normally leads to an increase in venous return to the right side of the heart, with an associated decrease in jugular venous pressure. In patients with lung disease, the “normal” inspiratory drop and expiratory rise in jugular venous pressure is amplified. This most likely occurs as a result of the exaggerated drop in inspiratory intrathoracic pressure and rise in expiratory intrathoracic pressure that occurs as a result of altered lung mechanics.
