Some references refer to “shunt-effect” or “dead space-effect” to designate the ventilation/perfusion mismatch states that are less extreme than absolute shunt or dead space. The following equation relates the percentage of blood flow that is not exposed to inhaled gas, called the shunt fraction Q s / Q t … See more 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 … 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 • Pulmonary shunt • Ventilation/perfusion ratio • Pulmonary contusion 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 $${\displaystyle Q_{t}}$$ is the total cardiac output See more Based on the Fick principle: By applying the Fick principle for the systemic and … 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 … See more WebHave the care team confirm your shunt setting if: You experience headache, persistent nausea, vomiting, drowsiness, weakness, seizures, slurred speech or worsening gait...
