WebNov 16, 2024 · A shunt can be quantified by measuring the flow ratio of the pulmonary cardiac output (Qp) to the systemic cardiac output (Qs). This flow ratio is the Qp/Qs ratio, otherwise known as the pulmonary-systemic shunt ratio. To calculate Qp and Qs, we can use the following shunt fraction equations: Qp = RVOT VTI × π × (RVOT / 2)². WebCardiac shunts may be: Left-to-right (acyanotic): This type of shunt doesn't affect the process of oxygenation in your lungs. Right-to-left (cyanotic): This type of shunt interrupts blood flow and oxygenation in your lungs.
