Although it ejects the same blood volume as the LV, the RV generates about one-sixth of its work and pressure, because the pulmonary vascular resistance is only about 15% of systemic vascular resistance (SVR).
In cases where the pulmonary vascular resistance increases, blood flows right-to-left across the VSD, producing cyanosis because more venous blood enters systemic circulation.

One of the most important things the RT can remember when caring for these patients is related to the pulmonary vascular resistance (PVR).
The pulmonary manifestations range from bronchospasm to an increase in pulmonary vascular resistance and pulmonary arterial pressure.
This action improves blood flow to ventilated alveoli resulting in reduced pulmonary shunting, decreased pulmonary vascular resistance, decreased pulmonary artery pressure, reversing of hypoxic pulmonary vasoconstriction in an obstructed airway which improves V/Q mismatching and an increase/improvement in oxygenation.
Initially the pulmonary vascular resistance is low, as PVR rises after birth, the pulmonary vascular resistance becomes equal to systemic and causes Eisenmenger, cyanosis, and bidirectional shunting.
Within 24 hours, the mean cardiac index was normal; mean pulmonary vascular resistance and pulmonary artery systolic pressure had declined significantly.
In the majority of patients, the postoperative course is characterized by a marked increase in cardiac output, with a concomitant decrease in pulmonary artery pressures and pulmonary vascular resistance (PVR) both immediate and sustained.
This study also suggested that NO acts with oxygen to reduce Pulmonary Vascular Resistance, (PVR) and their actions are additive in effect.
They also had significant drops in their pulmonary vascular resistance.
This right ventricular hypertrophy may be due to the decrease in the cross sectional area of the pulmonary circulation, which exacerbates regional alveolar hypoxia and leads to a downward spiral of increased pulmonary vascular resistance, increased work of the right ventricle, more hypoxia and on and on.
