Qp / Qs
(Last Updated - 12/28/2009)
-the form below uses the equation:
Qp / Qs =
VO2 / (PVO2 - PAO2) * Hgb * 10
VO2 / (PVO2 - MVO2) * Hgb * 10
Where:
VO2 = Oxygen consumption
PVO2 = Pulmonary Venous Sat = Wedge (PCWP) Sat
PAO2 = Pulmonary Arterial Sat
MVO2 = Mixed Venous Sat = [(3 * High SVC Sat) + IVC Sat] / 4
VO2, Hgb and the fudge factor of 10 cancel each other out
