WebJul 16, 2024 · In this topic, you study the definition, theory, formula, derivation & diagram of ammeter shunt resistance. The shunt resistance is essentially a low value resistance … 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 In echocardiography, we can measure the Velocity Time Integral (VTI). This is a clinical Doppler ultrasound measurement of blood flow, equivalent to the area under the velocity time curve. Based on the Bernoulli equation for incompressible fluids, … 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 … See more Based on the Fick principle: By applying the Fick principle for the systemic and … See more • Pulmonary shunt • Ventilation/perfusion ratio • Pulmonary contusion See more
