➡️ What is Jugular Venous Distention? (JVD)
Have you ever noticed someone with a vein in their neck that appears to be bulging out? If so, that vein is likely the jugular vein and it's a finding known as Jugular Venous Distention (JVD). The jugular veins run along the sides of the neck and function to move blood from the head to the superior vena cava, to the heart so that it can pass through the lungs for oxygenation. When the jugular veins are distended or visible in the neck, this is a sign of increased Central Venous Pressure (CVP).

➡️ What is Central Venous Pressure?
Essentially, the CVP measurement tells us how much blood is flowing back into the heart and how well the heart is moving that blood into the lungs and then to the remainder of the body. JVD is often a sign of Right Ventricular Failure and may also be seen in patients with obstructive pulmonary diseases. And it's also an indicator that the patient is fluid overloaded as well.

➡️ Causes of Jugular Venous Distention:
▪ Pulmonary hypertension
▪ Tricuspid valve stenosis
▪ Superior vena cava obstruction
▪ Constrictive pericarditis

If you or your patient has been diagnosed with a condition or are experiencing symptoms, as always, please speak with your doctor for medical advice and treatment.
