Shunt ratio
WebThe “Shunt Equation Calculator” is a tool used to determine the Shunt Equation Ratio, which represents the proportion of blood bypassing the lungs and not participating in gas … WebJan 7, 2024 · The ventilation/perfusion ratio is often abbreviated V/Q. V/Q mismatch is common and often effects our patient’s ventilation and oxygenation. There are 2 types of mismatch: dead space and shunt. Shunt is perfusion of poorly ventilated alveoli. Physiologic dead space is ventilation of poor perfused alveoli.

SHUNT RATIO QS = CCO2-CAO2 QT CCO2-CVO2 • CAO2 = O2 CARRIED BY HB + DISSOLVED O2 IN PLASMA = 1.34 X HB% … WebThe best way to quantify the shunt ratio (Qp/Qs) is to divide the blood flow in the main pulmonary artery (Qp) by the blood flow in the ascending aorta (Qs). In the case of an isolated ASD (i.e. no other shunts or regurgitant valve disease), Qp should equal the RV stroke volume, and Qs should equal the LV stroke volume.

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 receiving air, then it is perfectly oxygenated.
