Jugular venous pressure check

The jugular venous pressure test is an auxiliary examination method for checking whether the venous blood vessels are normal. The jugular vein is filled when the normal person is lying down on the pillow, but the jugular vein is collapsed when sitting or sitting half (ie, the upper body is at a 45 degree angle to the horizontal plane). In the sitting or semi-sitting position, such as the jugular vein is obviously filled, anger or pulsation, are abnormal signs. According to the level of jugular vein filling and pulsation, the level of central venous pressure can be indirectly estimated. A reliable reference point for central venous pressure is the sternal angle. The sternal angle is about 5 cm above the center of the right atrium, regardless of the patient's position in the semi-sitting or sitting position. Through this examination, the corresponding symptoms can be judged. Basic Information Specialist Category: Cardiovascular Examination Category: Other Examinations Applicable gender: whether men and women apply fasting: not fasting Tips: Before the check: taboo: maintain a normal diet and sleep. Normal value The jugular vein is filled when the normal person is lying down on the pillow, but the jugular vein is collapsed when sitting or sitting half (ie, the upper body is at a 45 degree angle to the horizontal plane). Clinical significance Abnormal result In the sitting or semi-sitting position, such as the jugular vein is obviously filled, anger or pulsation, are abnormal signs. People with cardiovascular disease who need to be examined. Precautions Taboo before the test: maintain a normal diet and sleep. Requirements for inspection: The neck examination should be carried out in a calm and natural state. It is best for the examinee to take a comfortable seat, untie the underwear and expose the neck and shoulders. If the patient is lying down, it should be fully exposed as much as possible. The technique should be gentle when inspecting, and should be noted when it is suspected that there is a disease in the cervical spine. Inspection process The patient takes a semi-sitting position or sitting position. The physician gently presses the external jugular vein with the finger above the clavicle. After the vein above the compression point is filled, the finger is released, and the distance between the jugular pulsation point and the horizontal line passing through the sternal angle is observed and measured. If it is greater than 4cm, it is estimated that the central venous pressure is greater than 9cm, that is, the venous pressure is increased, which is seen in right heart failure, constrictive pericarditis, pericardial effusion, superior vena cava obstruction syndrome, and increased chest and abdominal pressure.
