Therefore children with high pulmonary vascular resistance may not tolerate a Fontan procedure.

When the newborn takes its first breath, the lungs open and pulmonary vascular resistance decreases.

The systemic vascular resistance may also be referred to as the total peripheral resistance.

There are many factors that alter the vascular resistance.

This is possible due to the direct relationship between the cardiac output, mean arterial pressure and the vascular resistance.

This may, however, worsen hypertension by increasing the peripheral vascular resistance.

But loneliness produces an increase in vascular resistance it becomes harder for blood to move through the arteries.

It reduces mean arterial blood pressure by decreasing systemic vascular resistance.

Further, pulmonary vascular resistance usually drops back to close normal levels.

Vitamin C improves vascular resistance in patients with chronic renal failure.
