==Overview==

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. <br>

The V/Q ratio of a healthy lung is approximately equal to 1, which means the rate of alveolar ventilation to the rate of pulmonary blood flow is roughly equal.<br>
