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

What is Qp Qs in flow cytometry?

flow (Qp:Qs) is used to categorize the size of PDAs and corre- sponds to different clinical presentations.14 In cases where Qp:Qs < 1.5, the patient will often experi-

Does Qp/Qs ratio matter in cardiac catheterisation?

patients the Qp/Qs ratios obtained by PC-MRI and cardiac catheterisation fell at opposite sides of the cut-off value for clinical decision making of 1.5. PC-MRI would have suggested defect closure in these two cases, whereas oximetry would have led to a conservative
