QP QS Calculation CATH

Hey buddy can you please get the notes of Measurement of Qp:Qs in the
setting of congenital heart disease so that I can easily go through it?

[Kiran Chandar]

Feel free buddy I will help you here to get the notes of Measurement of Qp:Qs in the
setting of congenital heart disease so that you get idea about it.

Here is the detail about the notes

How is Qp best determined following bidirectional Glenn in the setting of single ventricle?

A.Phase contrast acquisition through the main pulmonary artery

B. Phase contrast acquisitions through the branc pulmonary arteries

C. Qp cannot be determined in this clinical setting

D. Phase contrast acquisitions through the pulmonaryveins

E.Phase contrast acquisition of the superior vena cava.

Methods to measure QP QS

Qp = Pulmonary flow

Qs = Systemic flow

Qp:Qs describes the magnitude of a cardiovascular shunt

Normally = 1:1

Left to right shunts >1.0

Right to left shunts <1.0

Qp:Qs is classically determined with oximetry via cardiac catheterization

Fick Principle

VO2 = (CaO2 - CvO2) * Q

Qp:Qs = (SatAorta-SatSVC)/(SatPulmonary Venous - SatPulmonary Artery)
