In our method the normal lung curve is approximated from The QP/QS ratio is calculated as A1/(A1-A2)as shown in Figure. 1E. Evaluation of the Method.

Qp:Qs ratio is very useful in many situations— such as in making decisions about surgery for a child with a ventricular septal defect where in a child beyond infancy a shunt producing a Qp:Qs > 1 8:1 is likely to require intervention while one of < 1 5:1 may be regarded as insig-ni?cant Qp:Qs is also helpful in assessing the
The QP/QS ratio (QP = pulmonary circulation and QS = systemic circulation) is calculated by dividing the surface area under the fitted curve (A1) by the difference between this surface area and the surface area under the fitted early recirculation curve
