18+ shunt calculation

Web The Shunt equation also known as the Berggren equation quantifies the extent to which venous blood bypasses oxygenation in the capillaries of the lung. Web The sex difference is less pronounced in the younger age groups and is largest in adults.

Hemodynamics Ii When The Waves Don T Look Right Ppt Download

Web The magnitude of an inra- or extracardiac shunt can be estimated by flow ratio between the pulmonary and systemic circulation QpQs using hemodynamic data.

. In conclusion we can calculate it. SF is the shunt factor. Web A shunt can be quantified by measuring the flow ratio of the pulmonary cardiac output Qp to the systemic cardiac output Qs.

Web The magnitude of an inra- or extracardiac shunt can be estimated by flow ratio between the pulmonary and systemic circulation QpQs using hemodynamic data. CcO 2 is the volume of blood in the ventilated alveoli End-pulmonary-capillary. SF CcO 2 - CaO 2 CcO 2 - CvO 2 where.
