This means “pulmonary circulation”. Definition. Pulmonary Ventilation / Perfusion Ratio The lung regions can be visualized as zones based on the degree of perfusion to those regions, which is greatly influenced by gravity ventilation-lung blood flow match is fairly similar in the gravitational direction, with a ventilation-to-perfusion ratio (V/Q) close to 1. In the upper regions V/Q may. 27 Jun 2009 Pulmonary imaging with ventilation/perfusion single photon emission tomography ventilatory rate and a high ventilation/volume ratio [38].

Watch the video for th Ventilation perfusion mismatch or "V/Q defects" are defects in total lung ventilation perfusion ratio. It is a condition in which one or more areas of the lung receive oxygen but no blood flow, or they receive blood flow but no oxygen due to some diseases and disorders. The V/Q ratio of a healthy lung is approximately equal to 0.8, as normal lungs are not perfectly matched., which means the rate of alveolar ventilation to the rate of pulmonary blood flow is roughly equal.
