Tīmeklis2024. gada 5. jūl. · The ideal V/Q ratio would be 1 for maximally efficient pulmonary function. However, the ratio varies depending on the part of the lung concerned. For … Tīmeklis2024. gada 13. janv. · V/Q ratio is the ratio between air getting into the alveoli and the blood flow to the lungs. Ventilation, perfusion, and V/Q vary in different lung regions because of the effect of gravity and the differences in the sub-atmospheric intrapleural pressure. Both ventilation (V) and perfusion (Q) are higher at the lungs' bases than at …
Tīmeklis2024. gada 26. febr. · A pulmonary ventilation/perfusion (or VQ) scan is a series of two lung scans. The scans are either performed together or one after the other, but are often referred to as one procedure. One of... Tīmeklis3.03.3.4.4.3 Perfusion and V / Q ratio A normal gas exchange within the lung relies on adequate perfusion and ventilation, but also on the two quantities being matched throughout the lungs. Accordingly, the ventilation–perfusion ratio () is a highly relevant parameter for the diagnosis of abnormal lung function, and especially its heterogeneity.
