Jugular venous pressure (JVP) is an indirect measurement of the pressure in the jugular vein in the neck, which can indicate heart problems or high blood pressure. It requires observation of the pulsations in the vein and can be measured in inches of water. It is often used in physical exams for patients with cardiovascular disease.
Jugular venous pressure (JVP) is an observation of the amount of pressure in the jugular vein in the neck. This is a form of indirect measurement, where the healthcare provider evaluates the patient by observation, rather than a direct measurement within the vein itself. People with certain heart problems may have jugular venous pressure abnormalities, and heavily swollen veins in the neck may indicate congestive heart failure or other serious health problems. A doctor may check a patient during a routine exam or follow-up if jugular venous pressure is a cause for concern.
Within the jugular vein, a distinct series of pulsations occur in connection with the heart rhythm. This vessel cannot be palpated like the neck artery; instead, people need to look at it to see the distinctive waves and descents of its movement. If these are out of rhythm, they indicate a problem. Similarly, an abnormally swollen jugular vein is a sign of high blood pressure, which is a symptom of some medical conditions.
To take this measurement, the doctor has the patient lie down and get comfortable, with the neck relaxed. The examination gown should be pulled across the chest to make the vein visible, and the patient’s chin may need to be lifted slightly and the hair pulled back. After the patient is in position, the observer can shine a bright light on the right side of the neck to highlight the jugular vein and watch it pulsate. It is also possible to measure the elevation of the vein to record a specific reading in the patient record.
Using the test measurements, the observer can report the jugular venous pressure in terms of inches of water. A similar unit of measurement can be used for direct measurement of blood pressure in medicine. Normal patients typically have an average measurement that can range from 6 to 8, depending on age, health, and gender.
This may be part of a physical exam for a patient with suspected cardiovascular disease or a patient on treatment who needs evaluation to determine treatment success. Measuring jugular venous pressure takes training and practice because each exam can be slightly different, and it takes time to learn how to identify jugular vein pulsations. In medical education, people have the opportunity to learn about such exams, observe people performing them, and conduct them under supervision to develop their skills.
