Since the right ventricle generates far lower pressures than the left ventricle ( approximately 20 mmHg versus around 120 mmHg, respectively, in the healthy individual ) but nonetheless generates cardiac output exactly equal to the left ventricle, this means that a small increase in pulmonary vascular resistance causes a large increase in amount of work the right ventricle must perform.
