Abstract

The mechanical properties of pulmonary blood vessels are essential factors influencing the distribution of pulmonary blood flow, regional volume distribution of blood and pulse wave propagation throughout the lung. These properties affect the pressure-flow relationship, and the change in total blood volume in response to an alteration in blood pressure. In order to formulate such problems, mechanical property data for blood vessels of all generations of the human lung are needed and are gathered in our laboratory. In particular, vessel diameter as a function of transmural pressure are measured for each vessel generation.
