venous return

Venous return is the rate of blood flow back to the heart.

The main difference is that the hand grip test does not increase venous return.

This increases systemic venous return, so more blood flows into the right side of the heart.

As an example, preload increases when venous return is increased.

The systemic venous return goes directly to the lungs, by-passing the heart.

For the first 14 hours post-operatively the foot of the bed is elevated to 45 to aid venous return.

Decreased venous return has the opposite effect, causing a reduction in stroke volume.

The maneuver can be done at any time during the respiratory cycle and it does not inhibit venous return to the heart.

Physiologically this means that air enters the lungs and venous return to the heart is enhanced.

One of Duomarco's favorite subjects of research was venous return regulation.

Although cardiac output and venous return are interdependent, each can be independently regulated.

Jet pilots wear pressurized suits to help maintain their venous return and blood pressure.

She was hoping for a disconnect between the two, because the venous return should lag by a mere fraction of a second.

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

Alternatively, squatting increases venous return and thus decreases the murmur.

Elevation aims to reduce swelling by increasing venous return of blood to the systemic circulation.

They are found in close proximity to arteries so that the pulsations of the artery aid venous return.

Preload is affected by venous blood pressure and the rate of venous return.

As venous return increases, the pressure in the superior and inferior vena cava increase.

Total anomalous pulmonary venous return is a structural problem with the heart that causes oxygen-poor blood.

Veinoplus activates the calf muscular pump which is responsible for 80% of the venous return.

Therefore right atrial pressure also alters venous return.

Stu drained the blood from the venous return lines, switched off the bypass machine, and started the stopwatch.

ESV + normal venous return will increase the end diastolic volume).

Venous return is to the Retromandibular vein.
