Venous Return

Venous return is a circulatory indicator that reflects the volumetric velocity of blood flow in the right atrium. It is an important indicator for assessing the functioning of the cardiovascular system and can help in the diagnosis of various diseases.

Venous return is defined as the difference between the volume of blood entering the right atrium from the veins and the volume of blood leaving it into the lungs. Normally, when the heart works normally, venous return strictly corresponds to the cardiac output. This means that the blood that enters the right atrium is completely returned to the heart and then to the lungs, where it is oxygenated and returned to the left atrium.

If venous return is reduced, this may indicate a problem with the heart or other organs. For example, in heart failure or pulmonary thrombosis, blood cannot return to the lungs in sufficient quantities, resulting in decreased venous return. In this case, the doctor may prescribe additional tests to diagnose the cause of the circulatory disorder.

In addition, venous return may be increased in some diseases. For example, if a patient has congestive heart failure, blood may be retained in the pulmonary vessels, increasing venous return. In such cases, the doctor may recommend treatment aimed at improving heart function and reducing blood congestion in the lungs.

Thus, venous return is an important indicator of blood circulation and can help the doctor in the diagnosis and treatment of various diseases of the cardiovascular system.

Venous return is a circulatory indicator that is measured in the volume of blood that the heart pumps per minute to the lungs. It is one of the key parameters when assessing the functioning of the cardiovascular system and its compliance with the needs of the body. This indicator is directly related to the work of the heart, which pumps blood from the body through the arteries into the veins, from where it enters the lungs and returns to the heart through the vena cava.
