The jugular venous pressure (JVP, sometimes referred to as jugular venous pulse) is the indirectly observed pressure over the venous system via visualization of the internal jugular vein. It can be useful in the differentiation of different forms of heart and lung disease .
Kussmaul sign suggests impaired filling of the right ventricle due to a poorly compliant myocardium or pericardium. This impaired filling causes the increased blood flow to back up into the venous system, causing the jugular vein distention (JVD) and is seen clinically in the internal jugular veins becoming more readily visible.

Wiggers with jugular venous waveform Wiggers diagram with mechanical (echo), electrical (ECG), and aortic pressure (catheter) waveforms, together with an in-ear dynamic pressure waveform measured using a novel infrasonic hemodynography technology, for a patient with severe aortic stenosis.
Thrombosis of the internal jugular vein can be displayed with sonography. Thrombi that have developed recently have low echogenicity or echogenicity similar to the flowing blood, and in such cases pressure with the ultrasound probe show a non-compressible jugular vein - a sure sign of thrombosis.
The jugular venous pressure is an indirectly observed pressure over the venous system. It can be useful in the differentiation of different forms of heart and lung disease . In the jugular veins pressure waveform, upward deflections correspond with (A) atrial contraction, (C) ventricular contraction (and resulting bulging of perspicuous into ...
The rising central venous pressure is evidenced by distended jugular veins while in a non-supine position. It is caused by reduced diastolic filling of the right ventricle, due to pressure from the adjacent expanding pericardial sac. This results in a backup of fluid into the veins draining into the heart, most notably, the jugular veins.
The jugular venous pressure (JVP) is the indirectly observed pressure over the venous system. It can be useful in the differentiation of different forms of heart and lung disease. The portal venous pressure is the blood pressure in the portal vein. It is normally 5–10 mmHg [39]
In some cases, fluids may be beneficial. Fluids can improve venous return. [7] For example, tamponade prevents normal cardiac filling due to pressure compressing the heart. In this case, giving fluids can improve right heart filling. [19] [26] However, in other causes of obstructive shock, too much fluid can worsen cardiac output. Thus, fluid ...
