Venous return information

Venous return is the rate of blood flow back to the heart. It normally limits cardiac output. Superposition of the cardiac function curve and venous return...

Anomalous pulmonary venous connection (or anomalous pulmonary venous drainage or anomalous pulmonary venous return) is a congenital defect of the pulmonary...

neurovascular bundle. This close proximity of the artery to the veins helps in venous return due to the pulsations in the artery. It also allows for the promotion...

insufficient venous return; the alternative name of varicose eczema comes from a common cause of this being varicose veins. Insufficient venous return results...

atrial reflex, is an increase in heart rate due to an increase in central venous pressure. Increased blood volume is detected by stretch receptors (Cardiac...

The jugular venous pressure (JVP, sometimes referred to as jugular venous pulse) is the indirectly observed pressure over the venous system via visualization...

Central venous pressure (CVP) is the blood pressure in the venae cavae, near the right atrium of the heart. CVP reflects the amount of blood returning to the...

venous return from the right lung (to the systemic venous drainage, rather than directly to the left atrium). This anomalous pulmonary venous return can...

enters the right ventricle. The increase in venous pressure after the y minimum occurs as venous return continues in the face of reduced ventricular...

cava (SVC) is the superior of the two venae cavae, the great venous trunks that return deoxygenated blood from the systemic circulation to the right...

Venous insufficiency can refer to: Varicose veins Chronic venous insufficiency Venous stasis This disambiguation page lists articles associated with the...

the negative intra-thoracic pressure results in an increased right venous return, filling the right atrium more than during an exhalation. The increased...

superficial venous reflux which is a treatable condition. As functional venous valves are required to provide for efficient blood return from the lower...

underlying problem is not the pump. Rather, the input into the heart (venous return) is decreased or the pressure against which the heart is pumping (afterload)...

lymphomas. In addition, diuretics (such as furosemide) are used to reduce venous return to the heart which relieves the increased pressure. In an acute setting...

partly muscular.[citation needed] The coronary sinus is responsible for venous return of about 55% of the cardiac blood supply. Electrodes can be inserted...

when venous tone (i.e the degree of venous constriction) is altered. This can be graphically depicted as changes in the slope of the venous return plotted...

often unclear. Cases may involve a combination of allergy and poor venous return. The type of dermatitis is generally determined by the person's history...

and increases venous blood flow velocity and valve effectiveness. Compression therapy helps decrease venous pressure, prevents venous stasis and impairments...

Venous thrombosis is the blockage of a vein caused by a thrombus (blood clot). A common form of venous thrombosis is deep vein thrombosis (DVT), when a...

posture for an extended period of time. It can occur due to diminished venous return of blood to the heart due to congestive heart failure or pulmonary hypertension...

speed of venous return will increase preload and, through the Frank–Starling law of the heart, will increase stroke volume. Decreased venous return has the...

plexus forms the chief mass of the cord. In addition to its function in venous return from the testes, the pampiniform plexus also plays a role in the temperature...

the circulation of blood. It is especially important in increasing venous return to the heart, but may also play a role in arterial blood flow. The skeletal...

collateral veins to bypass the blocked inferior vena cava and permit venous return from the legs. Determine the direction of flow in the veins below the...

sympathetic venous denervation. In these patients the selective Alpha-1 adrenergic receptor agonist midodrine may increase venous return, enhance stroke...

leading to an increase in heart rate and output, peripheral resistance, venous return and myocardial oxygen consumption, is not recommended in cardiac individuals...

their left side, pressure is relieved on the inferior vena cava, and venous return is not restricted. The cause of unconsciousness can be any reason from...

specificity of 96% in HOCM. Valsalva maneuver, as well as standing, decrease venous return to the heart. As a result, this decreases left ventricular filling....
