Direct influence of blood viscosity on pulmonary vascular resistance.
When cardiac output is maintained constant in the intact animal, changes in blood viscosity exert a direct and rapid effect on pulmonary vascular resistance. The presence of intact cardiopulmonary reflex mechanisms does not alter the direct influence of blood viscosity on pulmonary vascular resistance.
