Jugular venous pressure (JVP) by Nur Raihan Abdullah, undergraduate student, Faculty of Medicine, Universiti Teknologi MARA Defininition Jugular venous pressure is the blood pressure in the jugular veins, and is an indicator of the pressure of the right atrium. Occlusion: Gentle pressure applied above the clavicle will dampen the JVP but will not affect the carotid pulse. Define venous pressure and jugular venous pulse. Look for the right internal jugular vein (not external jugular vein) as it passes just medial to the clavicular head of the sternocleidomastoid muscle up behind the angle of the jaw in the direction of the earlobe. Venous pulsation usually returns to normal after a few seconds (even with continued abdominal pressure); if it remains elevated this suggests right-sided heart failure (Cox and Roper, 2005). This page includes the following topics and synonyms: Jugular Venous Distention, Jugular Venous Pulse, Jugular Venous Pulsation, Jugular Venous Pressure, Kussmauls Sign, JVD, JVP, Hepatojugular Reflux, Abdominojugular Test, HJR.

The mean jugular venous pressure is defined as a distance between the midpoint of the right atrium and the palpable jugular venous pulsation. Methods: We conducted a prospective anatomic study on a convenience sample of emergency department (ED) … Measuring jugular venous pressure (JVP) is a noninvasive physical examination technique used to indirectly measure central venous pressure(i.e., the pressure of the blood in the superior and inferior vena cava close to the right atrium). The level of the sternal angle is about 5 cm above the level of mid-right atrium in any position. However, the external jugular vein can become compressed as it enters th… In a hypovolemic foal, CVP is often 0 cmH 2 O or less. The paradoxical increase of the JVP with inspiration (instead of the expected decrease) is referred to as the Kussmaul sign, and indicates impaired filling of the right ventricle. A classical method for quantifying the JVP was described by Borst & Molhuysen in 1952. [1] It has since been modified in various ways. JVP measured in ANY position in which top of the column is seen easily. Understanding the Jugular Venous Waveform Normal Jugular Venous Waveforms There are two positive waves 'a' and 'v', one occurring just before the first heart sound or the carotid impulse, and one just after. Normal: 4 cm or less; Increased >4 cm (Jugular Venous Distention) Right-sided Heart Failure (most common) Increased Right Atrial Pressure; Constrictive Pericarditis; Tricuspid stenosis; Superior Vena Cava Obstruction; Valsalva phenomenon (laughing, coughing) Provocative: Hepatojugular Reflux. Only 33% IMR and 40% of GMP indicated a correct value and/or unit of measurement for normal jugular venous pressure (JVP). Measure the vertical height of the fullness seen as the jugular vein fills. The waveform that is seen immediately after the arterial pulsation is felt is the 'v wave' of the JVP. - Document the findings of whether the jugular venous pulsation is visible and, if so, whether it is normal … You will need good lighting preferably a penlight pointed tangential to the patient’s neck will accentuate the visibility of the veins.
