# Overview
Jugular venous pressure (JVP) is considered the most useful finding for assessing the ventricular filling pressures and central venous pressure (CVP) at the bedside. 
The jugular venous pressure is measured as the vertical distance between the top of venous pulsation and the angle of Louise, i.e., where the manubrium meets the body of the sternum. A distance of >3cm is considered jugular venous distension (JVD) or an elevated jugular venous pressure (JVP).

# Causes

## Life Threatening Causes
Life-threatening causes include conditions which may result in death or permanent disability within 24 hours if left untreated. 
- Acute heart failure
- Cardiac Tamponade
- Massive pulmonary emboli
- Right ventricular myocardial infarction
- Tension Pneumothorax

## Common Causes
Common causes of jugular venous distension include:  
- Congestive heart failure
- Cardiomyopathy
- Cor pulmonale
- Constrictive pericarditis
- Chronic obstructive pulmonary disease (copd)
- Fluid overload
- Pulmonary embolism
- Pulmonary hypertension
- Pulmonary valve stenosis
- Restrictive cardiomyopathy
- Right atrial myxoma
- Right heart failure
- Right ventricular myocardial infarction
- Tension pneumothorax

# Diagnosis
Shown below is an algorithm summarizing the diagnosis of jugular venous distension.    

# Treatment
- The management of jugular venous distension should be directed towards the underlying causes.    
- Treatment of congestive heart failure usually includes diuretics (for symptom relief), beta blockers, angiotensin converting enzyme inhibitors (ACE-I) /aldosterone receptor blockers (ARB).

- Treatment of right ventricular myocardial infarction includes reperfusion, maintenance of right ventricular preload, decreasing right ventricular afterload, restoring cardiac rate/rhythm and atrioventricular synchrony, and inotropic support.

# Do's
- If the JVP does not seem elevated when the patient is supine, a provocative test, i.e., abdominojugular test, might be performed.  By increasing venous return and pressure, the abdominojugular test, also known as hepatojugular reflux test, helps in better assessment of jugular venous pulsations.

# Don'ts
- JVD only provides clues to the presence of an elevated central venous pressure (CVP). 
- Clinicians should avoid making decisions about the degrees of CVP elevation based on the JVP measurement.
