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
