Contrast Echocardiography During Exercise to Assess Pulmonary Blood Volume

Capacitance is defined as the total volume of blood in an organ or region at a given pressure. Pulmonary Vascular Capacitance (ml/mmHg) will be determined by pulmonary blood volume/mean pulmonary artery pressure as measured with high fidelity micromanometer catheters in the pulmonary vasculature at rest during the standard of care exercise hemodynamic assessment.

Pulmonary blood volume (ml) is measured by measuring indicator dilution curves using sonographic contrast at rest during the standard of care exercise hemodynamic assessment.

Compliance is the change in volume for a given change in pressure. Pulmonary Vascular Compliance (ml/mmHg) is defined as stroke volume divided by Pulmonary Artery (PA) pulse pressure and will be measured with high fidelity micromanometer catheters in the pulmonary vasculature at rest during the standard of care exercise hemodynamic assessment.
