Meignan M, Simonneau G, Oliveira L, Harf A, Cinotti L, Cavellier JF, Duroux P, Ansquer JC, Galle P. Diagnostic difficulties occur in pulmonary embolism (PE) during visual analysis of ventilation-perfusion images in matched defects or in chronic obstructive lung disease (COPD). ventilation:perfusion ratio: (V̇V˙ A :Q˙) ( ven'ti-lā'shŭn-pĕr-fyū'zhŭn rā'shē-ō ) The ratio of alveolar ventilation to simultaneous alveolar capillary blood flow in any part of the lung; because both ventilation and perfusion are expressed per unit volume of tissue and per unit of time, which cancel, the units become liters of gas per liter Looking for ventilation:perfusion ratio?

Relación ventilación / perfusión - Ventilation/perfusion ratio De Wikipedia, la enciclopedia libre En fisiología respiratoria , la relación ventilación / perfusión ( relación V̇ / Q̇ o relación V / Q ) es una relación que se utiliza para evaluar la eficiencia y adecuación del emparejamiento de dos variables: Ventilatie / perfusieverhouding - Ventilation/perfusion ratio Van Wikipedia, de gratis encyclopedie In de ademhalingsfysiologie is de ventilatie / perfusieverhouding ( V̇ / Q̇-verhouding of V / Q-verhouding ) een verhouding die wordt gebruikt om de efficiëntie en geschiktheid van het matchen van twee variabelen te beoordelen: Let us take a closer look at the way alterations in the ventilation-perfusion ratio of a lung unit affect its gas exchange. Figure 5-6A shows the Po2 and Pco3 'n a unit with a normal ventilation-perfusion ratio (about 1—see Figure 2-1), The inspired air has a Po, of 150 mm Hg (Figure 5-1 ) and a Pco? of zero. Ventilation perfusion ratio (V/O) o Considering that cardiac output is 5.0 L/min and alveolar ventilation is about 4.2 L/min, the overall ventilation: perfusion ratio is 0-8. Idealy, therefore, each alveolus should have a V/Q ratio of 0.8. However, that is not so even in normal lungs.
