The pressure of the blood in the veins that aids in the return of blood to the heart.
Blood pressure in the right atrium of the heart, which cab be measured by means of a catheter.
A test to assess the heart’s ability to manage the volume of blood flowing through it. Special equipment is used to measure the trend of central venous pressure, more important in patients who require this measurement than a particular pressure reading by itself.
The pressure of blood within the right atrium of the heart as measured by a catheter and manometer.
The pressure within the superior vena cava. It reflects the pressure under which the blood is returned to the right atrium. The normal range is between 5 and 10 cm H20. A high CVP indicates circulatory overload (as in congestive heart failure), whereas a low CVP indicates reduced blood volume (as in hemorrhage or fluid loss). CVP can be estimated by examining the cervical veins or the dorsal veins of the hand if the neck and hand are at the level of the heart. Those veins are well filled if CVP is normal or high, and tend to collapse if it is low.
The internal force exerted within the right atrium, the cardiac chamber responsible for receiving deoxygenated blood from the body, is referred to as central venous pressure. To gauge central venous pressure, medical professionals employ a delicate tube connected to a monitor, which is carefully inserted through a vein in close proximity to the heart and into the right atrium. By continuously monitoring this pressure, physicians are able to approximate the quantity of blood circulating throughout the body. This procedure proves beneficial in cases of severe hemorrhage and instances where insufficient blood pressure hampers the delivery of an ample blood supply to organs and tissues.
