The amount of blood returned to the heart from the veins per unit time is called the venous return blood volume.

Difference between peripheral venous pressure and central venous pressure

venous resistance to blood flow

The volume of venous blood return to the heart is related to factors such as intravenous infusion speed, body position, and breathing.

Abnormal venous blood return to the heart may lead to heart failure, pulmonary edema and other diseases

Venous blood return to the heart helps diagnose and treat related diseases

Venous blood return to the heart is an important factor affecting heart function

Venous blood return to the heart is regulated by neural, humoral, and autoregulatory mechanisms

Neuromodulation includes sympathetic and parasympathetic regulation

Body fluid regulation includes the regulation of hormones such as the renin-angiotensin-aldosterone system, antidiuretic hormone, and atrial natriuretic peptide. Festival

Postural changes

Prevention: Prevent abnormal venous blood return through healthy lifestyle, reasonable diet, moderate exercise, etc.

Treatment: Take corresponding treatment measures according to different causes, such as improving heart pumping function and reducing venous pressure.

Laboratory tests: Assess venous blood return through blood tests, proper diet, diet and exercise, etc.

Clinical monitoring: Evaluate the volume of venous blood return to the heart through electrocardiogram, blood pressure, central venous pressure and other indicators Monitoring and evaluation of venous blood return to the heart
