WebA shunt is a small resistance that is connected to galvanometer to convert it into ammeter. An ideal ammeter has zero resistance. It is calculated through the formula. S = IGRG / I - … The Shunt equation (also known as the Berggren equation) quantifies the extent to which venous blood bypasses oxygenation in the capillaries of the lung. “Shunt” and “dead space“ are terms used to describe conditions where either blood flow or ventilation do not interact with each other in the lung, as they … See more The blood entering the pulmonary system will have oxygen flux $${\displaystyle Q_{t}\cdot Cv_{O_{2}}}$$, where $${\displaystyle Cv_{O_{2}}}$$ is oxygen content of the venous blood and Similarly, the blood … See more Based on the Fick principle: $${\displaystyle {\text{Cardiac Output}}={\frac {\text{oxygen consumption}}{\text{arteriovenous oxygen difference}}}}$$ By applying the Fick principle for the systemic and … See more • Pulmonary shunt • Ventilation/perfusion ratio • Pulmonary contusion See more The above equation requires measurement of the end-pulmonary-capillary oxygen content (CcO2) which is difficult to obtain and it is assumed to be equal to the alveolar oxygen content. This is based on the assumption that, if an alveolus is … See more In echocardiography, we can measure the Velocity Time Integral (VTI).
