WebNov 30, 2024 · Transjugular intrahepatic portosystemic shunt (TIPS) is an important therapeutic tool for patients with complications of portal hypertension (eg, variceal bleeding, refractory ascites). TIPS placement reduces elevated portal pressure by creating a low-resistance channel between the hepatic vein and an intrahepatic branch of the portal vein ... WebThe amount of oxygen from the shunt is calculated as shunt flow multiplied by the venous oxygen concentration (Q S x C V O 2), as shown in figure 15.3. The amount of oxygen going through the pulmonary capillaries can be described as the total volume minus the shunt volume (Q T −Q S) multiplied by the capillary oxygen concentration (figure 15.3).
