Central Venous Pressure (Cvp)

Central Venous Pressure (CVP) is an important indicator of blood circulation that reflects the blood pressure in the right atrium. It is measured by catheterizing the right side of the heart, with a pressure gauge attached to the catheter. Measuring CVP allows you to determine circulatory function, blood volume in case of bleeding or shock, and also monitor blood replenishment.

To understand the meaning of CVP, it is necessary to remember that the right atrium is the end point of the blood circulation and is located outside the systemic circulation. Therefore, CVP does not reflect the pressure in the arteries, but can give an idea of ​​​​the volume of circulating blood and the strength of cardiac activity.

CVP measurement is carried out when the patient is in a horizontal position, with the pressure gauge at zero in the center of the armpit. Under normal conditions, the central venous pressure should be between 5 and 8 cm of water column. However, it must be taken into account that CVP may differ in different patients depending on age, gender, physical activity, the presence of chronic diseases and other factors.

Changes in central venous pressure may indicate various pathological conditions. Increased central venous pressure may be associated with impaired cardiac function, pulmonary hypertension, impaired lymphatic drainage, or venous valve disease. A decreased central venous pressure may indicate decreased circulating blood volume, shock, anaphylactic shock, heart failure, or other pathological conditions.

Measuring CVP is an important diagnostic procedure for assessing the state of blood circulation and allows you to adjust the patient’s treatment if necessary. However, it must be taken into account that cardiac catheterization may be associated with certain risks and requires special training and supervision by medical personnel.

In general, CVP is an important circulatory indicator that allows you to assess circulating blood volume and cardiac function. Measurement of central venous pressure should only be carried out by a doctor in a specially equipped medical installation in compliance with all necessary safety measures and patient preparation.

Central Venous Pressure (CVP) is the blood pressure in the right atrium, which is measured using a catheter and a manometer.

CVP measurement is performed during catheterization of the right side of the heart and allows you to determine the body's circulatory function and blood volume in the event of severe bleeding or shock. CVP is also used to monitor blood filling after blood loss or other surgeries.

In a horizontal position, the central venous pressure should be between 5 and 8 centimeters of water with normal blood circulation. If the central venous pressure exceeds these values, this may indicate problems with the heart or blood vessels.

To measure CVP, a special catheter is used, which is inserted into the right atrium and attached to a manometer. The catheter measures blood pressure and determines how well blood is circulating in the body.

It is important to note that CVP measurement is an important diagnostic tool for many heart and vascular diseases. Therefore, if you suffer from any circulatory problems, it is recommended to regularly measure your central venous pressure and consult a doctor for advice.

What is CVP

In a healthy person, this pressure is negligibly low; it is in the range of 2-8 millimeters of mercury and can change under the influence of various factors. Body muscles increase blood pressure, fluid accumulated below increases the lower pressure threshold, chest tone can raise the empty capillary bed, blood flow in the lungs will affect the right atrium. These reasons cause it to contract, pushing blood to the upper part.

The normal pressure in this vessel is 5–6 millimeters of mercury. Its stable decrease is called the “shock index”, and is usually associated with dysfunction of the cardiovascular system. A normal decrease does not cause significant harm to the body, since the blood flow does not lose its usual parameters.
