Qp/Qs Calculator
A sample calculation is shown below
LVOT diameter
LVOT VTI
RVOT diameter
RVOT VTI
The equation for right sided cardiac output (Qp) over left sided cardiac output (Qs) is
Qp = [(RVOT diameter/2)^2*pi] * RVOT VTI
Qs = [(LVOT diameter/2)^2*pi] * LVOT VTI
pi cancels out since it is in the numerator and denominator so this =
(2.4cm/2)^2*23cm
(1.9cm/2)^2*22cm
= 33.2/19,9 = 1.7
