Physiologic Shunt = the alveoli is perfused but NOT ventilated (ex: Pneumonia causing an area of alveoli not to be well oxygenated but the area is still being perfused i.e. blood is still getting there) so the lung has opposite physiology to other tissues of the body where if an area is not being ...

WebPulmonary shunt. A pulmonary shunt is the passage of deoxygenated blood from the right side of the heart to the left without participation in gas exchange in the pulmonary capillaries. It is a pathological condition that results when the alveoli of parts of the lungs are perfused with blood as normal, but ventilation (the supply of air) fails ... WebIn respiratory physiology, the ventilation/perfusion ratio (V/Q ratio) is a ratio used to assess the efficiency and adequacy of the matching of two variables: . V – ventilation – the air that reaches the alveoli Q – perfusion – the blood that reaches the alveoli via the capillaries The V/Q ratio can therefore be defined as the ratio of the amount of air reaching the alveoli per …
