	Venous Pulse
		Venous blood returning from the systemic capillaries is nonpulsatile.Changes in flow and pressure caused by skeletal muscles and respiratory pump are nonsynchronous with the pulsatile activity of the heart.
		Venous pressure maybe estimated by examining the veins in the dorsum of the hand.
		The large "a" waves in the JVP during arrhythmias are present when the P wave (atrial contraction) occurs between the onset of the QRS complex and determination of the T wave (figure 203-g).such cannon "a" waves may occur regularly in junctional rhythm.

	Jugular venous pressure - Wikipedia, the free encyclopedia
		The paradoxical increase of the JVP with inspiration (instead of the expected decrease) is referred to as the Kussmaul sign.
		3.2 Differentiation of the JVP from the carotid pulse
		The JVP is easiest to observe if one looks along the surface of the sternocleidomastoid muscle, as it is easier to appreciate the movement relative the neck when looking from the side (as opposed to looking at the surface at a 90 degree angle).

	Physical examination of jugular venous pulse (JVP) is an integral part of cardiovascular examination... (Site not responding. Last check: 2007-10-22)
		Sometimes difficulty may be experienced in differentiating between the carotid and jugular venous pulses in the neck, particularly when the latter exhibits prominent V waves, as occurs in patients with tricuspid regurgitation in whom the valves in the internal jugular veins may be incompetent.
		Venous pressure may also be estimated by examining the veins in the dorsum of the hand.
		Normally there is an increase in the height of waves of the JVP with a decrease in the mean jugular venous pressure during inspiration as a result of the increased filling of the right-sided chamber associated with the decline in intrathoracic pressure.

	Pericardial Constriction
		Kussmaul's sign denotes an inspiratory increase in the venous pressure, which may occur in patients with severe constrictive pencarditis when the heart is unable to accept the increase in RV volume without a marked increase in the filling pressure.
		Accordingly, the occurrence of a positive wave in the JVP during ventricular systole is strong evidence of tricuspid regurgitation (Fig.
		A venous pulse characterized by a sharp y descent, a deep y trough, and a rapid ascent to the baseline is seen in patients with constrictive pericarditis or with severe right-sided heart failure.

		[3] In 1902, Mackenzie established the jugular venous pulse as an integral part of the cardiovascular physical examination, [4] and in 1928, Wiggers wrote that the jugular venous pulse might be useful in the interpretation of dynamic events in the heart.
		The tracing of the normal jugular venous pulse in the upper panel shows the A wave, the X descent interrupted by the C wave, and the V wave followed by the Y descent.
		It is exciting that late 19th- and early 20th-century interest in the jugular venous pulse and the third heart sound is reflected in the evidence-based, statistically analyzed investigation reported by Drazner et al.

		Jugular venous pressure is the vertical distance, measured in cm, between the venous pulsation in the neck and the sternal angle (junction of the second rib with the sternum) when the patient is propped up on pillows at 45 to the horizontal.
		Look for the jugular venous pulse in the internal jugular vein or its external jugular tributaries on both sides of the neck with the patient's chin tilted up and slightly away from you.

	Cardiovascular Examination
		This is a rough estimate of the systolic pressure.
		Maximum Cuff Pressure - When the baseline blood pressure is already known or hypertension is not suspected, it is acceptable in adults to inflate the cuff to 200 mmHg and go directly to auscultating the blood pressure.
		Pressure Differences - If there is more than 10 mmHg difference between the two arms, use the arm with the higher reading for subsequent measurements.

	Clinical Vignettes from CMI: Heart Failure
		Jugular venous pressure is estimated by measuring the vertical height of the internal jugular vein above the sternal angle (the junction of the manubrium and sternum).
		For this assessment, examining the neck veins for jugular venous pressure is crucial.
		Examination of the neck veins for jugular venous pressure is useful both for diagnosing heart failure and for monitoring response to therapy.

		The HJR test, defined as the venous pressure response to sustained abdominal compression, was performed in a standardized manner at the bedside assessing change in internal jugular venous pressure and during right-sided cardiac catheterization measuring change in right atrial pressure.
		The central venous pressure (CVP) could be predicted from the height of the jugular venous pulsations in 44 of 48 comparisons.
		Changes in venous pressure could not be attributed to changes in esophageal pressure or to compression of the heart by elevation of the diaphragm.

	Jugular vein - Wikipedia, the free encyclopedia
		The internal jugular runs with the common carotid artery and vagus nerve inside the carotid sheath.
		The JVP can be raised in a number of conditions, such as right ventricular failure (heart failure), tricuspid stenosis, tricuspid regurgitation and cardiac tamponade[2].
		As the internal jugular is large, central and relatively superficial, it is often used to place venous lines.

		Cannulation of the internal jugular vein may be the method of choice to measure the central venous pressure because of the lower incidence of complications.
		The right internal jugular vein is usually chosen, since the right lung is lower than the left and this route does not endanger the thoracic duct.
		Identify the anatomical landmarks : the internal jugular vein lies lateral to the carotid artery; the sternocleidomastoid muscle overlies the internal jugular vein in the lower half of the neck (photo 3).

	The Jugular Venous Pressure - Patient UK
		The Jugular Venous Pressure or JVP is the height in centimetres of the venous wave form in the internal jugular vein, measured vertically from the sternal angle with the patient reclining at 45°.
		The external jugular waveform may be used as a guide to the JVP if there is clearly no obstruction to the flow of blood in the vein, ie the height varies with posture and abdominal pressure as above.
		A raised JVP with absent waveform is seen in superior vena caval obstruction, in association with engorged head and neck veins and plethora.

	Constrictive Pericarditis MEDSTUDENTS-CARDIOLOGY (Site not responding. Last check: 2007-10-22)
		This pattern of venous return contrasts with that in cardiac tamponade, in which cardiac compression is present throughout diastole, so that the diastolic surge is blunted or abolished such that the atria fill during ventricular ejection in early systole and the venous pressure tracing shows absence of or blunted diastolic y descent.
		Another striking abnormality of constrictive pericarditis is the failure of intrathoracic pressure changes during respiration to be transmited to the pericardium and intracardiac chambers.
		A minority of patients may survive for many years with modest jugular venous distension and peripheral edema that is controlled by the judicious use of diet and diuretics.

	Physical examination findings are important in predicting outcomes in heart failure, researchers report
		In a retrospective analysis of a large heart-failure trial, published in today's issue of The New England Journal of Medicine, researchers found that patients with either a third heart sound or elevated jugular venous pressure were more likely to have progressive heart failure and subsequent hospital visits due to heart failure.
		The researchers also found that the subgroup of patients with a third heart sound or elevated jugular venous pressure had a significantly higher risk of death.
		Physicians assess jugular venous pressure by observing the pulsations in the jugular veins visible in the neck.
